COMPOSITE PARTICLE, PRODUCING METHOD THEREOR, AND COMPOSITE COMPOSITION AND COMPOSITE BLENDED WITH THE COMPOSITE PARTICLE

摘要

PROBLEM TO BE SOLVED: To obtain composite particles which combine the excellent characteristics of silica, titanium oxide and calcium carbonate, to provide a method for producing the particles, and to provide a composite composition and a composite blended with the composite particles. SOLUTION: In the composite particles, silica particles an titanium oxide particles are stuck to the surface of synthesized calcium carbonate. The composite particles can be produced by adding silica and titanium oxide in a carbonating reaction stage of a production process for synthesized calcium carbonate.
