METHOD FOR MANUFACTURING INORGANIC OR METAL FINE GRAIN- CALCIUM CARBONATE COMPOSITE GRAIN, COMPOSITE COMPOSITION AND COMPOUND MATERIAL CONTAINING THE COMPOSITE GRAIN

摘要

PROBLEM TO BE SOLVED: To provide an inorganic or metal fine grain-calcium carbonate composite grain having characteristics of calcium carbonate itself, and having intrinsic characteristics of various inorganic or metal fine grains, a composite composition or a compound material containing the grains.;SOLUTION: The inorganic or metal fine grain-calcium carbonate composite grain is manufactured in a way that, before or in the middle of a carbonation reaction by CO₂ combining method generating the synthetic calcium carbonate, at least 1 kinds of inorganic or metal fine grains excluding silica and titanium dioxide which indicate negative zeta potential when dispersed into water, and indicate positive zeta potential when dispersed into limewater are added therein, thereby, the inorganic or metal fine grains and the generated calcium carbonate grains are firmly fixed.;COPYRIGHT: (C)2003,JPO
