Synthesise β-tricalcium phosphate (β-TCP) ceramic powder by 2 reaction steps: hydrothermal and calcination reaction toward bone tissue regeneration

Abstract

This research presents the effect of heat treatment temperature on the forming ability of β-tricalcium phosphate (β-TCP) bioceramic materials toward the bone tissue regeneration application. Ca(OH)2 and H3PO4 were mixed with a Ca/P molar ratio of 1.5, followed by hydrothermal treatment at 180oC for 24 hours to obtain the calcium phosphate hydrate (CPH) with phase composition similar to hydroxyapatite (HA). The CPH mineral was heat-treated at 700 and 1000oC for 3 hours to evaluate the ability to obtain β-TCP. The result showed that β-TCP can be obtained by the CPH calcined at 1000oC for 3 hours, with the particle size of 1~2 µm, suitable for bone tissue regeneration application.
