Beschreibung
Zusammenfassung:	PURPOSE: A bio-active combined ceramics composition is provided to eliminate problems of conventional apatite ceramics and improve bio-activity by combining the apatite with wollastonite. CONSTITUTION: The composition is produced by combining the apatite(Ca10(PO4)6)X (wherein X is any one selected from O, (OH)2, CO3, F2, Cl2) and the wollastonite(CaSiO3) in weight ratio of 5:95 to 90:10; pressing the composition or conducting a molding process of the composition to obtain a porous form; and sintering the molded form at 1200-1400 deg.C. The wollastonite is generally synthesized by blending calcium oxide and silica in 1:1 mole ratio. 본 발명은 생체친화성이 우수하나 생체활성이 떨어지는 아파타이트 세라믹스의 단점을 해결하여 아파타이트에 월라스토나이트를 복합함으로써 아파타이트나 월라스토나이트의 단일 세라믹스보다 생체활성을 크게 개선한 인공골용 생체활성 복합 세라믹스 조성물 및 그 제조방법에 관한 것이다. 본 발명은 분말로 이루어진 아파타이트(Apatite, Ca(PO)X, 여기서 X=O,(OH), CO, F, 및 Cl중 어느 하나임)와 월라스토나이트(Wollastonite, CaSiO)를 중량비로 5:95에서 90:10으로 조성하여 조성물을 준비하는 단계와, 상기 조성물을 가압하거나 다공체로 성형하여 성형물을 얻는 성형 단계와, 상기 성형물을 소결 처리하는 단계로 조성되는 것을 특징으로 한다.
