Patent ID: 7416564

Claim:
A method for manufacturing a porous bioceramics for bone scaffold comprising the steps of: forming a biocompatible porous ceramic substrate having the property to thermal-decompose hydroxyapatite in contact with it, wherein the average size of pores in said porous ceramic substrate is 100 micron or more, and the pores are connected with each other; coating a fluorapatite (FA) inner layer on said porous ceramic substrate; and coating a hydroxyapatite (HA) outer layer on said fluorapatite inner layer, wherein the step of coating the HA outer layer comprises the steps of immersing the formed porous ceramic substrate coated with the FA inner layer into HA slurry and drying it; and thermal-treating the formed HA outer layer, and wherein the step of thermal- treating comprises sintering at a temperature in the range of from about 1200° C. to about 1250° C.
