AN SSSR, 1956, vol 11, pp 64-75 ABSTRAC~: The genus of diatomaceous alga Rouxia Brun and Heri- baud is described in detail. AN exhaustive critical purvey of the literature concerning this fossil genus is made. The genus Rouxia is a connecting link be- tween genera having i-utures on one Valve only and true Diraphineae with sutures on both valves. There is a very close kinship, apparently, between Rouxia and Peronia, which has rudimentary sutures on only one of Card 1/2 its valves. The genus includes four species.

The determination takes place by precipitation of niobium with a 3~o' aqueous solution of cupferron from hydrochloric solution, containing one of the three mentioned complex-forming compounds. The precipitate is filtered off, annealed and then decomposed with potassium pyrosulfate. After cooling, a solution of oxalic acid, ammonium oxalate or tartaric acid is added, wherein the melt is soluble on heating. The solution obtained is acidified with hydrochloric acid and Card 113 precipitation of niobium with cupferron is repeated. The Determination of Niobium in the Presence of SOV/75-14-1-13/32 Tungsten by the Aid of Cupferron precipitate obtained is annealed (,-,10000) and weighed out as Nb205' The precipitation with cupferron takes place at room temperature. Filtering and washing of the precipitate is rapid and reliable. The results obtained from the determination shov that for determining niobium. in the presence of tungsten all three mentioned complex formers are suitable to the same degree for the masking of tungsten. By the aid of the radioactive isotope w185 the precipitates of Nb205 were investigated as to their tungsten content. The amount of tungsten co-precipitated was found to be dependent on that of niobium. On precipitating 10 mg 14b in the presence of 100 mg W more pure Nb205containing no tungstcn is obtained. Investigation of the precipitates that are obtained from the alloys 71 - Si - Nb showed co-precipitation of tungsten to occur only ~,,tith niobium contents > 30%.

TITLE: Determination of Niobi 7in C~ast IFron PERIODICAL: Akademiya nauk SSSR. Institut metallurgil. Trudy, No.4, 1960. Metallurgiya, metallovedeniye, fiziko-khimicheskiye metody issledovaniya, pp.240-242 TEXT: The object of this work was to find a method of determining niobium in cast iron in the presence of iron and titanium, without their preliminary separation. Ascorbic acid C6H8O6 was used to form a complex with titanium and for reducing iron to the bivalent form in which it stays in solution. After preliminary experiments the following procedure was developed. 1-1.5 g of the sample is treated with 5 ml of 1.40 s.g. nitric acid. After evaporation almost to dryness on a sand bath, the solution is completed by adding 30 ml of 1:2 hydrochloric acid and boiling. The volume of the solution is maintained by adding water. Ignoring any black light residue the solution is diluted to 180-190 mi, 1-2 g of ammonium chloride and 0.1-0.2 g of ascorbic acid are added and the temperature is raised to 70-80 OC. Card 1/3 S/509/60/000/004/022/024 Elll/E152 Determination of Niobium in Cast Irons 10 ml of freshly prepared 10.0' aqueous tannide solution are slowly added with stirring, the heating being continued for 2-3 hours. Macerated paper is added and after cooling the precipitate is filtered and washed 6-8 times with cold 4% hydrochloric acid. The precipitate and paper are heated in a platinum crucible until all graphite has burned off. A few drops of water, 10-20 drops of 1:1 sulphuric acid and 2.3 ml of hydrofluoric acid are added and the crucible is gradually heated on a sand bath until S03 fumes have been evolved for 5 min. 1-2 ml of water are added to the cooled crucible and evaporation is carried out until only 2-3 drops of sulphuric acid remain. After cooling, 1-2 ml of water and 5 ml of hydrochloric acid (s.g. 1.19) are added and the crucible is heated until all salts have dissolved. The solution is transferred to a beaker, diluted to 80-90 ml and the n1oblum is precipitated as before after addition of 0.10 g of ascorbic acid.

TITLE: Determination of zirconium and niobium in their binary alloys using cupferron PERIODICAL: Zhurnal analyticheskoy khimii, v. 17, no. 3, 1962, 327-329 TEXT: A rapid and precise method for the determination of zirconium and niobiurn in their binary alloys, based on the successive precipitation of these elements using cupferron. A review of the problem in the literature is given. Works of Alimarin and Schr6der are cited and adapted. The results of a series of determinations of Nb and Zr in synthetic solutions containing tartaric acid are tabulated and the error calculated. The error varies in this case between 0-3% (relative). The method of analysis of solutions containing Zr and Nb in a ratio of 1:1 and 3:1 is identical with that described here for samples of unknown composition. PROCEDURE: 1) Determination of zirconium - 0. 1 g of the sample is dissolved in a Pt-crucible by addition of 2-3 ml KF and a few drops of HN03 to the complete dissolution of the alloy. Then 3-4 ml H2S04 (SP- 9r = 1.84) are added and heated in a sand bath, for 10-15 min. until white vapors appear and all the HNO, is removed. After cooling, 25 ml 4% solution of tartaric acid and 10 ml 2% soln. of NHsfluoridc are added and the solution is transferred to a 300 ml beaker. The solution (100-125 ml), is neutralised by Card 1/2 Determination of.. S/075/62/017/003/003/004 1017/1217 ammonia using phenol-red indicator: the color changes from red, through yellow, to red; 2 drops ammonia are added in excess.The solution is cooled to room temp. and Zr is precipitated by addition of 10-15 ml 6 % aqueous cupferron soln. which is added slowly with stirring, the soln. is left in the cold one night. The preci- pitate is filtered off using a filter of 9 cm. bt (white band), and washed 5-6 times with cold water. The precipitate with the filter paper is placed in a weighed Pt or porcelain crucible, ignited for 10-20 min. at 1000'C, cooled in a desiccator and Zr02 is weighed. The factor for Zr calculation from ZrO2 is 0.7403. 2) Determination of niobium - 50 ml 2 % soln. of boric acid, 5 ml HCI, 20-25 ml 6 % aqueous soln. of cupferron are added to the filtrate obtained after the separation of the Zr by vigorous and constant stirring V to complete coagulation of the precipitate. After filtration carried out under the same conditions as for the Zr separation, the 20 ml 6% aqueous cupferron soln. The precipitate with the filter is ignited in Pt or porcelain crucible for 15-20 min. at 1000'C cooled in a desiccator and the Nb201 weighed. The factor for the Nb calculation from Nb2O, is 0.6990.

The dissolution of a1loy is accomplished w1ith HP and ENO sub 3 in a plati- nun crucible with a subsequent additi 'on of H sub 2 SO sub 4. The method is based on the precipitatioh of niobium with cupferron ata pH of 4.6 in presence of tar- taric acid which complexes the molybdenum. The present method is more accurate than the existing hydrolytic methods which show low results when compared to Stan- dard solutions. Orig. art. has: 2 tables.

Analysis of results of heating of abutment boundary contact pipe billets under rolling in muffles of carbon steel and steel B1847 shows that even under' h conditions of very thorough degreasing of surface of these billets, pipes become inclined to intercry3talline corrosion; heating in muffles of carbon steel is accompanied by appearance Of significantly larger inclination of free surface of steel E1847 clad pipes to intercrystalline corrosion than during heating in muffles of steel E1847- It was established also that clad pipes are the less able to resist corrosion, the more hermetic the packing of the muffle in which billets for these pipe3 are heated. Azid only heating of billets under rolling without 'muffles (on hearth of continuous furnace) ensures obtaining of clad pipes not ,inclined to intercr-ystalline corrosion. This is explained by the fact that during 11 heat treatment on hearth of continuous furnace products of combustion of remainders of lubricant, adsorbed in microdefects and micropores of steel EI847 are wall eliminated, which cannot be achieved with usual chemica3 methods of degreasing. :Furthemore, in hermetically closed muffles heightened pressure is created, ii 'increasing diffusion rate of C of remainders of adsorbing lubricant in depth of V metal, and process of oxidation of surface proceeds less intensely, Intercrystal- it Card 2/3 - F bMSTAK, G.A., kand. tekhn. nauk Recurrence of basic parameters of one-story i#ustrial buildings of the machinery industry.
