PURPOSE:To provide the magnesium compound-coated particles suitably used as a compounding material or filler for resin molded products, films or coatings, inks, paper, etc., and further suitable as a catcher for polymerization catalysts, to provide the method for producing the particles, and further to provide the resin molding, coating, or ink compounded with the particles. CONSTITUTION:The magnesium compound-coated particles comprise constant shape nucleus particles and a magnesium compound used for coating the constant shape nucleus particles the constant shape nucleus particles comprising at least one from amorphous silica, amorphous silica-alumina and amorphous aluminosilicate salt in which each particle has independently a clear three- dimensional to spherical primary particle shape and further has a primary particle diameter of 0.3-20mum measured with an electronic microscope. |
