Abstract
A porous and spherical calcium phosphate particle which is substituted with a metal ion or has a metal ion carried on the surface thereof, and has a particle diameter of 0.1 to 100 μm. The calcium phosphate particle is a novel functional particle which is useful, for example, as a material for use in gas chromatography allowing the separation of a chemical substance of a trace amount with high accuracy.
