HOT PRESS PRODUCTION AND MECHANICAL PROPERTIES OF SYNTHESIZED CARBONATE HYDROXYAPATITE OF GEL MONOLITHIC ORIGIN

This investigation shows that by a drastic increase in the pressure at hot pressing sintering there are possibilities to increase the fracture stress value and the mechanical strength of the carbonated apatite samples. It is also possible to obtain carbonate hydroxyapatite, containing the same carbonate content as from the start. However, the temperature should be kept below 1073 K. In this case, the final product will have a mechanical strength lower than that of bone. The carbonate hydroxyapatite is biocompatible.
