ABSTRACT:
An inorganic particulate material comprising fine balls approximately uniform in size and 0.1 to 50 .mu.m in mean particle size and prepared by admixing an aqueous solution of at least one compound (i) selected from among halides of alkaline earth metals, inorganic acids, organic acids, ammonium salts or inorganic acids, ammonium salts of organic acids and carbonates of alkali metals with an aqueous solution of at least one inorganic compound (ii) selected from among silicates, carbonates, phosphates or sulfates of alkali metals, halides of alkaline earth metals, and sulfates, hydrochlorides or nitrates of copper family elements o iron family elements before or after admixing an organic solvent (iii) with said aqueous solution of at least one inorganic compound (ii) to form a W/O emulsion, said compound (i) being capable of forming a water-insoluble precipitate when subjected to an aqueous solution reaction with said inorganic compound (ii).
