抄録

This study was conducted to obtain a fine powder of β-tricalcium phosphate as a startinig material of high strength calcium phosphate ceramics. Calcium-deficient hydroxyapatite was synthesized by the trituration and reaction of a slurry, a mixture of calcium hydrogenphosphate dihydrate and calcium carbonate at the molar ratio 2:1 prepared in a pot mill. for 24h. Calcium-deficient hydroxyapatite was converted to β-tricalcium phosphate by the calcination at 750°C for 1h. The average particle diameter and specific surface area of the synthesized β-tricalcium phosphate were 0.44μm and 27.4m²/g, respectively. The present method was superior to the previous dry process: 1) no requirement of adjustments of pH value and reaction temperature, 2) lower calcination temperature, and 3) easy preparation of a fine powder of β-tricalcium phosphate.
