摘要
This paper reports methods related to the synthesis of bioceramics containing apatite and calcium zirconium orthophosphate as main crystalline phases. The phases were identified by XRD. The chemical stability of these materials was determined by treating crushed samples with 0.2 M TRIS-HCl buffer solution at a temperature of 37degreesC for 120 hrs and measuring of the ions leached out by the ICP-OES method. The solubility of the synthesised materials is lower than that of hydroxyapatite especially for decreasing pH values.
