摘要：

Monetite and hydroxyapatite have been synthesized by hydrothermal treatment of monocalcium phosphate monohydrate (MCPM) suspension at 160 degreesC and 200 degreesC. The monetite formed whiskers typically having length, diameter and aspect ratio in the range of 26-40 mum, 1-2 mum and 20-26, respectively and the hydroxyapatite shaped needle like crystals typically being in the range of 0.2-0.5 mum in length and 0.02-0.04 mum in diameter. The morphology of the crystals seems to be controlled mainly by the solubility of the reactant species. The phase of the hydrothermal product is determined by,the combination of the pH and the Ca/P ratio of the aqueous solution. The whiskers obtained can be used as a bioactive reinforcement for composites. (C) 2001 Elsevier Science Ltd. All fights reserved.
