Calcium phosphate mineral compositions and methods for preparing same
Abstract
Calcium phosphate minerals are formed by using phosphoric acid substantially free of uncombined water in conjunction with a calcium source, normally as any combination of carbonate, phosphate and hydroxide, and, as required, any additional base to neutralize the phosphoric acid. Protein may be optionally added. The resulting product is readily formed and then sets to a hard, stable, workable shaped object.
