Bone ash: Difference between revisions

'''Bone ash''' is a white material produced by the [[calcination]] of [[bone]]s. Typical bone ash consists of about 55.82% [[calcium oxide]], 42.39% [[phosphorus pentoxide]], and 1.79% [[water]].{{cln|reason=The<ref>'Review unitOn ofDifferent "%"Parameters isAnd meaninglessUses here,Of becauseBone thereAsh' isS. noSahithi, contextL. orManasa, anG. explanationAnusha, whatS.v. percentKrishna signV. standsTejeswara forRao.

Bone ash usually has a [[density]] around 3.10&nbsp;g/mL and a [[melting point]] of 1670&nbsp;°C (3038&nbsp;°F). Most bones retain their cellular structure through calcination.
