METHOD OF PREPARING POROUS CALCIUM PHOSPHATE GRANULES

摘要

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.
