| Abstract |
β-tricalcium bis (orthophosphate) [Ca3(PO4)2] (β-TCP) was mechanochemically treated
with mortar grinder. The ground β-TCP was hydrolyzed in an aqueous ammonium solution
(pH=11.0) at 90 to give Ca-deficient HAp involving small amount of CO3
2- ions. With an
increase in grinding time of β-TCP, it was hydrolyzed easily. Well-crystalline Ca-deficient HAp was
obtained after grinding of β-TCP for 7 hours and the successive hydrolysis. |
