ABSTRACT

Calcium phosphates recognized as important bio-materials have been successfully synthesized by simple precipitationusing waste abalone shells, which are rich mineral sources of calcium. Calcium hydroxide (Ca(OH)2) originated from abalone shells was used as calcium source (precursor) for the preparation. Synthesis of calcium phosphates was performed by reacting calcium hydroxide with phosphoric acid (H3PO4) in aqueous solution. The initial precursor Ca/P ratios were adjusted to 1.50, 1.59 and 1.67, and the effect of the composition and the heat treatment on the synthesized powders and sintered bodies was investigated. The phases of the sintered ceramics prepared at 1150°C were hydroxyapatite (HAp), β-tricalcium phosphate(β-TCP), and biphasic phosphate (HAp with β-TCP)), which were determined by the initial precursor Ca/P ratios. The results demonstrate the possibility for the synthesis of high value-added calcium phosphates from economical starting materials with low cost and high availability.
