METHODS FOR SYNTHESIZING ALKALI METAL SILICATE AND ALKALI METAL SILICATE INCLUDING TRANSITION METAL, AND ALKALI METAL SILICATE AND ALKALI METAL SILICATE INCLUDING TRANSITION METAL

摘要

PROBLEM TO BE SOLVED: To provide a method for synthesizing an alkali metal silicate which is easily microparticulated, and to provide a method for synthesizing, with the use of the alkali metal silicate, an alkali metal silicate including a transition metal.SOLUTION: The alkali metal silicate is synthesized by: preparing a basic solution including an alkali metal sa mixing the basic solution including the alkali metal salt with silicon particles to form a basic solution including the alkali metal silicate; and adding the basic solution including the alkali metal silicate to a poor solvent for the alkali metal silicate to precipitate the alkali metal silicate. Further, the alkali metal silicate is mixed with a microparticulated compound including a transition metal to form a mixture, and the mixture is subjected to heat treatment, whereby the alkali metal silicate including the transition metal is generated.
