Abstract

Hydroxiapatite with stabilised or unstabilised zirconia ceramics were synthesised by solid state-reaction of oxide powders. Their sinterability as we l as phase analysis were studied by X-ray diffraction analysis. The microstructure of sintered materials was investigated by scanning electron microscopy (SEM) and EDAX. The ceramic and some mechanical properties were investigated using a comparative approach. An interaction mechanism between zirconia and its polymorphs with calcium phosphates existing or formed after sintering is discussed..
