METHOD FOR PRODUCTION OF METASILICATES OF ALKALINE-EARTH METALS, MAGNESIUM AND LEAD Russian patent published in 1998 - IPC

Abstract RU 2104928 C1

FIELD: glass boiling. SUBSTANCE: metasilicates of alkaline-earth metals are prepared by their precipitation of aqueous reaction medium which comprises compound of metal and alkaline-silicic solution, the process is followed by separation and heat treatment of desired product. Filtrate which is prepared by partial precipitation of silicate of liquid glass by preliminary purified compound of metal (being of the same kind as desired metasilicate) is used as mentioned above alkaline-silicic solution. EFFECT: improved efficiency of the method. 1 tbl
