ABSTRACT: A oakined measuring device for the remote determination of some
Physical-chemical liquid constants, viz. density, viscosity. and
solidifio~Ltion-melting tezTerature is described. The principal part
of this device is a vessel into which a certain quantity (about 5 ml)
of the liquid to be investigated is introduced by way of a siphon.
For the purpose of measuring viscosity the device was first thenw-
statized at a given temperature for 30-60 minutes. Hereupon under-
pressure was produced In the pipette, the liquid rose up to the level
of the electrodes, the systan was oonneoted with the outer air, and
the liquid ma able to emerge freely from the capillary. A oompari-

ABSTRACT: The ternary system thallium-selenium-tellurium was izriraztigated
by measuring the specific conductivity, by investigating the
microstructure and,by the aid of the thermal analysis. The
microstructure was investigated by a metal microscope MlM-5-
The synthesis of the samples was carried out by melting the
chemically pure metals in evacuated vessels. For the surface
construction of the liquid 94 alloys were examined and the
phase diagram was plotted. The system has no ternary
eutectics nor ternary compounds. Five crystalline zones are
formed. In the first crystallization zone primary separation
of tellurium and selenium takes place. In the second zone
solid solutions between TlSq and TlTe are formed. Solid

TITLEt Dispersion of Silicic Acid Gel in Acid Media 1;ith the Aid
of Ultrasonic Vibrations
PERIODICAL: Kolloidnyy zhurnal, 1959, Volume XXI, Nr 4, PP 388-391
(USSR)
ABSTRACT: The authors report on experiment's intended to homogenize
with the aid of ultrasound a highly acidic solutton, in
which silicic acid has sedimented in the form of a gel.
A first series of experiments was carried out for the pur-
POS6 ~f ascertaining the ability, of ultrasound to trans-
iorm polymerized forms of silicic acid into the monomeric
state. The solution subjected to ultrasound treatment con-
tained 4 gli Sio and 4 N M10 . The samples differed from
2 i
one another concerning the ag~ of the silic ac d gel. Table
2 shows that the ultrasound treatment results in an increase

frequency from 6 to 3 megacycles, as well as of the duration
of the ultrasound treatment from 10 to 120 minutes has practi-
cally no effect on the final result. It was observedv howeverp
that the quantity of dispersed sediment was very small. Full
dispersion depends on a number of factors: ultrasound fre-
quency/age of gel and composition (particularly acidity) of the
solution. Table 3 shows the results of experiments in which
these factors were suitably considered. It became evident
that the dispersion effect increases with the diminution of
ultrasound frequency. Pull transformation of the gel into a
sol was obtained at a frequency of 1.1 megacycles. The data
show that the quantity of monomeric SiO obtained by the ul-
trasound treatment is inconsiderable. Tfie quantity of this
form of S102 characterizes that*portion of ultra-sound energy
which is spent in chemical action, i.e. for the break of the

energy at ^-..,6 calories for 1 ml of solution with a silicic
acid concentration of 4g/l. The low yield of monomeric SiO',
is explained as being due to polymerization of sili3ic acid.
The high acidity of the solution and the heat produced dL-ril-Ig
ultrasound treatment favor this process. The authors menll-.ion
the Soviet scientist S.S.Rzhevkin, who developed a theory on
the dispersing effect of ultrasound, There are 3 tables and
6 references, 5 of which are Soviet and 1 English.

T1=-E- Nature of ultrasonic depolymerization of silicic acid gel
PERIODICAL: Kolloidnyy zhurnal, v. 24, no. 3, 1962, 259 - 262
T:.:XT: The concentration and temperature de.pandonces of the phase state
of sio2 and the nature of ultrasonic depolymerization of silicic acid gel
vere studied. G. Schmid's theory (PhYs. Z. 41, 325, 1940) on frictional
f-orces between macromolecules and liquid causing polymer rupture, was
studied by means of ihe splittipg of silicic acid polymers whose structure
changes with the concentration. The measuring device (Fig.) consisted of
(1) quartz plate (vibrator), (2') polished brass rings, (3) metal rods, (4)
auartz holder, (5) reflector. Ultrasonic waves of,1000 kc.p.s. and
-1-5 w/cm 2 were applied. Systems with 3 - 106 g/liter SiO 2 and .I
4 - 5 g-equiv/liter MHO 3were studied. The gel ripened for 50 days at 20
- 0
and 70 C. Sonic irradiation was continued until complete homogeneity was

The ripening temperature has practically no affect on depolymerization.
