Description: 
In 1933, the Laboratory of Silicate Chemistry was organized in 
Leningrad. In 1948, it was reorganized into the present Institute. 
The Institute conducts fundamental research on the physical chem- 
istry of silicates. It has studied the synthesis of inorganic high polymers 
and new methods of synthesizing organosilicon compounds. Studies of sili- 
cates containing rare earths have been initiated in the Institute's labora- 
tories. It has done conspicuous work in the study of the interaction at 
high temperatures of calcium-aluminum silicates and compounds that contain 
fluoride. 
The Institute has developed new methods of grinding and polishing 
glass. It built the first Soviet high-temperature microscope, used to study 
processes that take place at temperatures up to 2800 C, to observe effects 
such as wetting, to determine melting points, and to study crystallization 
processes. 
The Institute also has worked on the synthesis of isoprene.
