The invention describes a method of preparing macroporous calcium
phosphate granules with NaCl porogen technique, wherein a calcium
phosphate self-setting cement powder is mixed with 30 to 80 wt % NaCl.
The calcium phosphate granules comprise macro- and micropores
communicating with one another substantially throughout the body with a
porosity of 40% or more and having the same mineral as those of human
bones. Said granules are used as a substitute or repairing material for
bone, carrier material for drug delivery and gradual release system.
