Abstract
The purpose of the present invention is to provide a plasma spray material which is capable of forming a hydroxyapatite film that exhibits high adhesion strength with respect to substrates such as metal substrates. When used as a plasma spray material, hydroxyapatite powder having a modal diameter of 550-1000 nm in a pore diameter of at most 5000 nm as measured by a mercury intrusion method is capable of forming a hydroxyapatite film that exhibits high adhesion strength with respect to substrates such as metal substrates.
