ABSTRACT:
Disclosed is an amorphous, spherical inorganic compound having a particle size of 0.1 to 1.0 .mu.m, which comprises as main constituents (1) an oxide of at least one metal selected from the group consisting of metals of the Groups I, II, III and IV of the Periodic Table, said metal oxide being capable of combining with silicon dioxide, and (2) silica.
This amorphous, spherical inorganic compound is prepared by a process comprising adding a mixed solution containing a hydrolyzable organic silicon compound and a hydrolyzable organic compound of at least one metal (M) selected from the group consisting of metals of the Groups I, II, III and IV of the Periodic Table to an alkaline solvent capable of dissolving said organic silicon compound and said organic metal compound therein but substantially incapable of dissolving a reaction product of both the organic silicon compound and the organic metal compound therein, effecting the hydrolysis to precipitate the reaction product and, if necessary, calcining the reaction product.
