PRODUCTION OF HYDROXY APATITE

PRODUCTION OF HYDROXY APATITE

PURPOSE:To obtain the titled compound having a desired Ca/P ratio in a short time in good reproducibility, by adding CaO and/or Ca(OH)2 to slurry of CaHPO4.2H2O and water to give a solid reaction product, and heating it. CONSTITUTION:CaO And/or Ca(OH)2 is gradually added to and reacted with slurry o...
