Description

(54) СПОСОБ ПОЛУЧЕНИЯ ВЫСОКОКРЕМНИСТОГО КРИОЛИТА(54) METHOD FOR OBTAINING A HIGHLY SILICONE CRYOLITE

Claims (2)

Формула изобретенияClaim 1. Способ получения высококремнистого криолита путем взаимодействия алюминййсодержащего и кремнефторсодержащего соединений с содой с последующим отделением и сушкой полученного осадка, отличающийся тем, что, с целью повышения скорости фильтрации, в раствор алюминийсодержащего соединения вводят сначала соду до pH = 4-5, затем кремнефторсодержащее соединение и снова соду до pH 5-7.1. A method of producing a high-silicon cryolite by reacting an aluminum-containing and silicon fluorine-containing compounds with soda, followed by separation and drying of the obtained precipitate, characterized in that, in order to increase the filtration rate, soda is first introduced into the solution of the aluminum-containing compound to pH = 4-5, then the silicon-fluorine-containing compound and again soda to pH 5-7. 2. Способ поп. 1, отличающий с я тем, что в качестве алюминийсодержащего соединения используют раствор фтористого алюминия или фторалюминиевой кислоты, а в качестве кремнефторсодержащего соединения используют кремнегель, содержащий фтористый алюминий.2. The method of pop. 1, characterized in that a solution of aluminum fluoride or fluoroaluminic acid is used as an aluminum-containing compound, and silica gel containing aluminum fluorine is used as a fluorine-containing compound.
