It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). Calcium phosphate is one of the main combustion products of bone (see bone ash). Calcium phosphate is also commonly derived from inorganic sources such as mineral rock.〔Yacoubou, Jeanne, MS. (Vegetarian Journal's Guide To Food Ingredients ) "Guide to Food Ingredients". The Vegetarian Resource Group, n.d. Web. 14 Sept. 2012.〕 It has three crystalline polymorphs α, α' and β. The α and α' states are formed at high temperatures. As rock, it is found in Whitlockite. ==Nomenclature== (詳細はorthophosphates (PO43−), metaphosphates or pyrophosphates (P2O74−) and occasionally hydrogen or hydroxide ions. Especially, the common mineral apatite has formula Ca5(PO4)3''X'', where ''X'' is F, Cl, OH, or a mixture; it is hydroxyapatite if the extra ion is mainly hydroxide. Much of the "tricalcium phosphate" on the market is actually powdered hydroxyapatite. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tricalcium phosphate」の詳細全文を読む スポンサード リンク
