【 摘 要 】
Calcium phosphates (CP) have been synthesized by sol-gel method in various calcium to phosphorus molar ratio and calcination temperatures. The objective of this study was to understand the influence of molar ratio Ca/P and calcination temperature on crystalline phase of CP. Sol-gel synthesis of calcium phosphates have been performed at room temperature by mixing calcium nitrate and phosphoric acid at Ca/P molar ratio 1.0, 1.3 and 1.5. Gel of synthesis products were dried at 110°C to produce powder then measured by thermal analysis of Differential Scanning Calorimetry-Thermogravimetric Analysis (DSC-TGA). Powders of CP were calcined at 110, 400 and 600°C based on thermal analysis result. Crystalline phase and chemical bonds of calcined CP powders were characterized by X-Ray Diffractometer (XRD) and Fourier Transform Infrared Spectrophotometer (FTIR).
