摘要:
A method for producing a calcium phosphate-based material comprising:(a) molding a calcium phosphate powder;(b) preliminarily calcining the resulting molding in a vacuum or under a reduced pressure until the relative density is 95% or more; and(c) firing the molding in air, an inert gas, or nitrogen gas.
