Изобретение относитс к технологии .силикатов и может быть использовано в производстве циркона, муллита, форстерита и других тугоплавких силикатов.This invention relates to silicate technology and can be used in the production of zircon, mullite, forsterite and other refractory silicates.
Известен способ получени тугоплавких силикатов, например циркона, путем приготовлени шихты, Пропитки ее водным раствором соли щелочного металла, снекани и отмывки .A method of producing refractory silicates, such as zircon, is known by preparing a mixture, impregnating it with an aqueous solution of an alkali metal salt, and removing and washing it.
Цель изобретени - увеличение выхода силиката.The purpose of the invention is to increase the yield of silicate.
Цель достигаетс тем, что в качестве соли щелочного металла используют гидроокись в количестве 0,5-5 мл %.The goal is achieved by using hydroxide in the amount of 0.5-5 ml% as the alkali metal salt.
Иример; Высушенный гель совместно осажденных гидроокиси циркони и кремнекислоты , содержащей 2,65 г ZrOz и 1,47 г Si02, измельчают и пропитывают 0,5 мл раствора едкого лити , содержащего 0,051 г ZiOH. Затем массу обжигают при температуре 1000°С в течение 0,5 час и обрабатывают с.месью серной и плавико1вой кислот. Остаток промывают и высушивают. Иолучают 3,73 г ZrSi04 белоснежного цвета.Irimer; The dried gel of co-precipitated zirconium hydroxide and silicic acid containing 2.65 g of ZrOz and 1.47 g of Si02 is crushed and impregnated with 0.5 ml of a solution of caustic lithium containing 0.051 g of ZiOH. Then the mass is burned at a temperature of 1000 ° C for 0.5 hour and treated with a mixture of sulfuric and hydrofluoric acids. The residue is washed and dried. Iolize 3.73 g of white snow-colored ZrSi04.
Выход готового силиката составл ет 94,5%.The yield of finished silicate is 94.5%.
