摘要：

In the present study, apatite powders were obtained from aqueous precipitation under different pH values. The produced powders were used as a base material for the production of porous bioceramics. Porous samples were produced by a dry method using organic additives and sintering at 1100degreesC. The powders were sintered and characterised by X-ray diffraction. The final microstructure consists of hydroxyapatite and tricalcium phosphate. Scanning electron microscopy analysis showed an interconnected porous structure with pores larger than 100mum. This method of production of porous bioceramics is simple and does not involve the use of commercial hydroxyapatite. These findings represent an alternative method for the production of triphasic porous ceramics.
