Investigation of microwave sintering process of biogenic hydroxyapatite at 900 °C

Abstract

In the present work the microwave sintering process of biogenic hydroxyapatite at 900 °C for 5—30 min has been investigated. It was established that the sintering time practically did not effect on the structural and mechanical properties of ceramics. The fine hydroxyapatite ceramic with uniform pore distribution and porosity equal to 39—40%, which has a compressive strength 37—42 MPa and is close to natural bone strength, can be obtained at 900 °C for 5 min. It can significantly reduce the cost of the final material.
