Abstract

Beta-tricalcium phosphate (β-TCP) is a biomaterial that is widely used as bone scaffold and calcium phosphate cement. β-TCP has excellent characteristic such as biocompatible, highly solubility, and faster degradation rate than other types of calcium phosphate. In this research, β-TCP was synthesized from natural limestone and phosphoric acid. The synthesis method used is wet precipitation method. Phosporic acid solution was added by titration at rate of 0,5 mL per second. Temperature reaction controlled at 60⁰C meanwhile calcination process at 800⁰C and 1000⁰C. The mineralogy characteristic by  X-Ray Diffractometer (XRD) showed that β-tricalcium phosphate main phase was formed at 800⁰C and while characterization of chemical content with X-Ray Flourescence (XRF) β-TCP has a Ca/P molar ratio of 1,35-1,37.

Abstract

Dicalcium phosphate is one of the apatite materials used for precursors to synthesize other apatite materials such as tricalcium phosphate, tetracalcium phosphate, and hydroxyapatite. Apatite materials are widely used in the medical field and pharmaceutical industry. This study aims to prepare dicalcium phosphate from natural limestone as a precursor for apatite with an easy-to-apply method for industrial scale. Wet precipitation process was performed to prepare dicalcium phosphate from phosphoric acid and slaked lime or calcium hydroxide with reaction temperature control at around 60⁰C and at pH of 3-4, then drying is carried out at about 180⁰C. The product is characterized for its mineral content by XRD and EDX. Semi-quantitative calculation of the synthesized material contains more than 90% dicalcium phosphate andhydrous, the rest is other apatite minerals. It can be used as a precursor for apatite production.
