Abstract
Calcium phosphate minerals are formed by using highly concentrated phosphoric acid in conjunction with a calcium source, normaly as carbonate or a combination of carbonate and hydroxide, optimally in conjunction with calcium phosphate crystals and 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.
