摘要:
A method for making calcium phosphate particles, the method including compressively pulverizing a molded body containing, as a principal component, a calcium phosphate material with a plurality of parallel extending needlelike projections. The molded body contains a plurality of void holes oriented in one direction and the pulverizing is carried out by moving the needlelike projections in a direction of protrusion, which is aligned with the one direction. Each needlelike projection has a diameter within a range of 1.0 to 2.0 mm and a number the needlelike projections per unitary surface area is within a range of 5 to 35 per cm2.
