METHOD OF PRODUCTION OF THE LIQUID GLASS Russian patent published in 2008 - IPC C01B33/32 

FIELD: chemical industry; other industries; methods of production of the liquids glass.

SUBSTANCE: the invention is pertaining to the method of production of liquid glass applied in the production of the deposited silica. The method of production of liquid glass used in the production of the deposited silica - the white soot provides for mixing of the silica-containing stuff and the solution of the sodium hydroxide, the hydrothermal treatment of the produced suspension, separation of the remainder by filtration and its cleansing. In the capacity of the silica-containing stuff use the remainder after leaching of serpentinite by the mineral acid, which contains the particles with the coarseness in the fractions with the step of 0.3-0.4 mm, the lower limit of the first fraction is 0.1 mm, and the upper limit of the last fraction - 1.2 mm. The technical result of the invention is expansion of the raw materials base for production of the high quality liquid glass used for production of the deposited silica and reduction of the material costs.

EFFECT: the invention ensures expansion of the raw materials base for production of the high quality liquid glass used for production of the deposited silica and reduction of the material costs.
