摘要：
A method of preparing a low crystallinity calcium phosphate apatite is described in which a low crystallinity calcium phosphate is precipitated from an aqueous solution comprising calcium and phosphate ions; collected from the solution; and dehydrated in a humidity and at a temperature selected to minimize growth and promote conversion to calcium phosphate apatite. The resultant calcium phosphate apatite is block solid of improved strength, porosity and bioresorbability.
