Simple sodi= silicates contg TiO2 crystallize with sepn of TiO2 as cryst phase only if they contain little Na2O or SiO2. Only 20% TiO2 is required to give a transparency 223T26 eliminating effect tc these melts. Partial replace- ment of SiO2 or Na, 0 'with boric anhydride, ZnO and especially A120 increases the transparency elimi- nating power ana causes the melt to crystallize with a lower TiO2 content. CaO and BaO reduce this power and cancel the effect of the above substances, Melts contg boric anhydride have high surface luster. The index of reflection of white enamels'of this type, produced on an industrial scale and applied on steel, was 70 - 75%. Presented by Acad 1. V.

The high chemical stability of these glass samplea is attributed to their high alumina content and very high con- tent of niagnesi= oxide, Some glass samples contained up to 25% cal- cium and ma&nasium oxides. The invertigation tends to prove that a high-lovel glass industry existed already in pre-MonEollan Russia. Thret ref-irences. Tables.

The introduction of K20, BaO, and Ca6 hindered the crystal- 'lization of Ti02- On the other hand,' the introduction of ZnO, MgO, and, especially, B20~ and A1203 favored this crystallization. Quoting sources from the literature, the authors show that, for a majority of natural silicates, the coordination number of titanium is six. It is possible that titanium with a coordination number of 4 is present in pyroxenes and amphiboles, where the element iso- morphously replaces silicon. It is suggested that titanium in glasses may be found with coordination numbers of both four and six. The ease of separating rutile from enamel that contains Mg and Zn indicates that the T102 has not undergone any fundamental change in the enamel, i.e., the titanium preserves its coordination number of six without change. When the melt contains Mg, Zn, and, especially, B, i.e., substances that have a strong R-0 bond of sufficient magni- tude and which tend to increase the coordination number, titanium oxide begins to crystallize with smaller amounts of it in the melt.

In order to investigate the possibility of reducing the light absorption of industrial types of glass it is necessary to find out the composition cf the contaminating additions and their sources. For this purpose the method of the analysis of the curves of spectral absorption was used. The concentrationE of the coloring matter can be determined by means of a mentioned scheme of formulae when some conditions are met, Investigations showed that in spectrophotometric glass analyses only the following 6 color additions may be expected: Fe2039 FeO5 Cr2O.V V 205 + VO 2' HiO and CoO. In figure 1 the Card 1/3 curves of the coeffioients of the specific absorption of the The Effect of Contaminating Additiong on the Light Absorption 72-58 -5-8/18 and Color of Glasses six mentioned ooloring oxides are listed and then described in detail and explained.

There are two methods of using high frequencies for the purpose of melting glass: the method of the electric field and that of the magnetic field. For the method of the electric field a frequency of 20-25 kc will be sufficlent, and melt:hig can be carried out at room ta.Verature without any preheating. For the method of the magnetic field additional furnaces with an additional equipment for preheatinS the layer is necessary, which renders this method less valuable. The idea of melting glass by the method of the elec- tric field was first developed in the USSR by A.V.Makarov, who, in 1941, succeeded in obtaining glass by means of a high-frequenoy system of 10 V.,T and 75 ke frequency In a crucible bAving a cubic Card 1/2 capacity of 100 cm.3. Two apparatus of this type, UVCh-80 and The Melting of Glass in a High-Fraquenqy Electric Field 72-- ,8 -6-6/ig UVCh-'2200, are at present in operation in the USSR; their pcq,,rer output is 80 and 200 k`#7 respectively. Fig. I shovws the a-aparatus UVOh-80, which is also described. A double q:aartz crucible Yrith interspace, filled up with crashed fira clay was found to be the most suit,ea. Fig. 2 shows the cooling of the plates by m,~ani of a spiral -1.,4be which --s solderea on. Control of the smelting process can be carried o~at according to efficiency and temperature. In the high-frequency system a number of multicolored as well as of optical types of glass, and of such as are particularly difficult to smelt was smelted, the temperature attained amounting to up to 18000. By the -smelting method of the electric field it is possible to obtain glass vrith a very low degree of light absorption. In the case of smelting carried out in an electric field the crucible is less liable to become corroded than in a reverbatory furnace. Th~ entire process of glass smelting takes place in an atmospherB of oxidation, which fact exercises a favorable effect upon light ab- sorption. The degree of efficiency of these plants is consiJerably higher than that of reverbator7 furnaces, and the quality of glazas is partly better. These systems can be used with good success both in production and in experiments. There are 2 figures, and I r--f,- erence, 0 of wbich is Soviet. Card 2/2 1. rila'ss--Melting 2.

TITLEr Cerium Dioxide as a Clarifying and Decolorizing Agent of Glass PERIODICAL: Steklo i keramikap 19609 Nr 2, pp 22 - 26 (USSR) ABSTRACT: In order to investigate thoroughly the decolorizing effect of cerium dioxide, the authors studied the absorption-spectrum cu a of glasses. At the same time also the clarifying effect of '~ ium was investigated. Further, papers by V. V. Pollyak, R.!'Grich vt kaya, P. A. Stabrovsk.ayao K.

Cerium dioxide is mentioned as the best-known chemical decolorizing agent of glass, which transforms up to 99% of irbri in glasses into Fe203. The amount of CeO- if. ig and decolorizing glass fiu.-' necessary for glaryi -,;uates between 0.15'~g '(in the case of "Polyrit", 0-30 ;- 0-80%) and depends on mel ng conditions, glass composition, and its m e I nr content of iron oxides.

Leadless enamels should, however, be preferred because of the deleterious action of lead compounds ~ V. V. Vargin and M.V.Serebryalcova also worked in this field. The present paper deals with further investi- gations of leadleas, thinly liquid silica glasses and the preparation of high-quality industrial enamels for aluminum, Titanium dioxide reduces the viscosity, increases the resistance against water and acid and in- creases the light refraction and reflection. For their experiments, the authors melted a number of glasses of the composition Na 20-2(sio2+TiO 2) and with varying TO 2 content,. A. V. Senderovich, Candidate for Diploma, and A. F. Kurbatova, Laboratory Assistant, participated in these Card 1/3 Glasses of the System Na2 0 - TiO 2 - Si02 as Basis of Enamels for Aluminum S/072/60/000/010/003/004 B021/BO58 experiments. The fusibility was determined by the method of the Chair for Glass of the Leningradskiy tekhnologicheakiy. institut imeni Lensoveta (Leningrad Technological Institute imeni Lensovet) (Fig. 1).. Glass No. 13 was synthetically produced on the Easig'-o-f -the results, At a temperature of 5700C, it has a good flow on aluminum and has a sufficient resistance against water, acetic acid (0) and citric acid (10%)~ The results of the determination of chemical stability and the fusibility of the glasses are shown in Figs. 2 and 3, Enamel compositions for aluminum were worked out on this basis for the practice, and they are tabulated as followst Oxide Percent by weight Molecular percent Sio2 36.6 38,0 TiO2 24~7 19,3 B 203 4.0 3.5 Na20 30.7 30.8 Li20 4,0 8.4 The introduction of lithium oxide and boric anhydride in limited Card 2/3 Glassee of the Bystem Va 0 - TiO, - SiUS) Lie S/072/60/000/010/003/004 2 B021/BO58 Basis of Enamels for Aluminum quantities improved the fusibility and did not affect the chemical stability. A partial replacement of Na 20 with X20 (up to 20 mol percent) increased the fusibility, but had a deleterious effect on the water and acid resistance. The opaque appearance of the enamel was improved by the replacement of a small quantity of TO 2 with Al 2039 although this resulted once again in a decrease of chemical resistance.

The fusibility was determined in terms of temperature which glass powder - water mixtures gave smooth flowing Amongst those tested were glasses containing 20 % less and 20 more of P 205 as compared with the metaphosphate,, Almost all glasses,/ with P 205 deficiency tended to crystallize while those with P 205v excess~ although they did not crystallize, exhibited low chemical resistance. Chemical analysis has shown that in glasses with a F2 05 content exceeding that of metaphosphates, the phosphoric anhydride vaporized at a rate proportional to the temperature. All those- glasses were unstable when fixed on the metal and caused foaming of enamels. It was found that simple-metaphosphatesp excluding lead metaphosphate, do not form glasses suitable for use in low meltin6 enamels.

Considering the system as a tetrahedron with Na20 at its apex the glasses studied-were on five sections with Na 20 contents of 10, 15t 20, 25 and 30 mol ~j (the maximum for adequate chemical stability). Chemical stability in water and 4 % acetic acidt and covering properties were investigated. The best composition (mol ~*) was: A1203 7.5 - 10, ZnO 20 - 25, Na 20 15 - 25t P205 45 - 60.

Stability is very sensitive to the Zn content and with a definite oxide ratio (P 205+ A1203)/(Na20 + ZnO)--- 1 zinc can change its coordination number from 6 to 4 and partly enter the glass lattice. As regards coating qualityl these phosphate glasses were not much improved by increasing the alkali content; high (over 10 mol ~o) alumina contents gave poor coatings.

Glasses were developed which are superior to those used by E. Snitzer. Absorption and luminescence spectra were obtained, and the dependence of the duration of luminescence on concentration was determined. Induced emission was observed both in glass fibers encased in glass and in highly homogeneous glass cylinders. The dependence of time characteristics and spectral composition of induced emission on pumping energy was established.
