Hydroxapatite (HA) is a stable phase with low dissolution rate in body fluid. Meanwhile, tricalcium phosphate (TCP) is rather soluble but the dissolution rate is too fast for bone bonding. Therefore a mixture of both is desirable to control the bioresorbability. In this work, calcium phosphate powder has been synthesized via sol gel and wet precipitation method to compare phase behaviour
Zincdoped biphasic calcium phosphate (BCP) powders have been synthesized via solgel method. The dopant concentration ions were adjusted at 1, 2, 3, 5, 10 and 15 mol%.
Abstract. Biphasic calcium phosphate (BCP) is a mixture of nonresorbable hydroxyapatite (HA) and the resorbable tricalcium phosphate (TCP) is an interesting material for bone imp
Zincdoped biphasic calcium phosphate (BCP) powders have been synthesized via solgel method. The dopantud concentration ions were adjusted at 1, 2, 3, 5, 10 and 15 mol%. The powders have been calcined at varying temperatures ranging from 500900 #176;C and then characterized by XRD, FTIR, TG/DTA, TEM and FESEM data.

This paper discusses the dependence of microstructure and mechanical properties of sintered biphasic calcium phosphate (BCP) on sintering temperature and compacting pressure of BCP dense bodies. BCP nanopowders were prepared via hydrothermal method using eggshell as the calcium source, followed by compaction into circular disc shape at various pressure and sintered pressureless in air at

Incorporation of metal as sintering additive is a simple way to improve physical and mechanical properties of biphasic calcium phosphate (BCP) materials as well as its performance in biomedical applications. In this work, magnesium (Mg) was incorporated into the BCP as sintering additive to improve the properties of BCP. The aim of this work was to study the effect of Mg doping to the BCP on
