Abstract

In this work the characteristics of microwave sintering of porous hydroxyapatite ceramics have been investigated. It was established that use of microwave sintering at 1000 °C provides to obtain ceramics based on biogenic hydroxyapatite with porosity of 35 – 46,5 % that was 90 – 95 % open, and compressive strength 21 – 67 MPa. It was shown that increase of compacting pressure from 50 upto 250 MPa promotes the formation of a fine-grained ceramics with particle size 0,06 – 1,37 μm and reduction existence interval of the most pores down to 0,2 – 0,7 μm.
