Description
Изобретение стпоситс к способам получени гидроокиси бари путем обжига смеси карбоната бари и кремнезема с образованием трехбариевого силиката К последующим разложением трехбариевото силиката водою.The invention relates to methods for producing barium hydroxide by burning a mixture of barium carbonate and silica to form three-barium silicate K, followed by decomposition of three-baric acid to silicate with water.
Предлагаемый способ в сравнении с известными дает возможиость получать гидроокись бари непосредственно из природных соединений бари , в частности из минерала витерита , и ускор ет процесс образо1вани трехбариевого силиката.The proposed method, in comparison with the known ones, makes it possible to obtain barium hydroxide directly from natural barium compounds, in particular from the mineral viterite, and accelerates the process of formation of three-barium silicate.
Особенность предлагае.мого способа состоит в том, что обжиг смесн карбоната бари и кремнезема ведут в присутствии добавок марганцевого шлама или окиси железа, или itx смеси в количестве I-2% от общего веса шихты.The peculiarity of the proposed method is that the firing of a mixture of barium carbonate and silica is carried out in the presence of additives of manganese sludge or iron oxide, or itx mixture in the amount of I-2% of the total weight of the mixture.
Способ осу1цествл етс с.чедуюпщм образом.The method is realized in a simple manner.
Берут смесь карбоната бари и кремнезема в соотношении 3;1, добавл ют к смеси марганцевый шлам, или окись железа, или их смесь в количестве 1-2% от общего веса щихты и ведут обжиг при температуре 1100°. После обжига образовавшийс трехбариевый силикат подвергают гидролизу и получают гидроокись бари .A mixture of barium carbonate and silica in a ratio of 3; 1 is taken, manganese sludge or iron oxide is added to the mixture, or a mixture of them in an amount of 1-2% of the total weight of the mixture and calcined at a temperature of 1100 °. After calcination, the resulting three-baric silicate is hydrolyzed and barium hydroxide is obtained.
