中文百科
骨灰骨灰一般指遗体于火葬后所剩余的遗骸。遗骸在火化后只会留下白色的骨骸，若再加以研磨，会是白色粉末，成份主要是磷酸钙。磷酸钙常见于肥料、润饰化合物和制陶业（骨瓷）中。历史上也曾用于制作烘焙粉末和金属提炼炉。 虽然现在已经有骨灰的合成替代物，但骨瓷的主要成份仍然是天然的动物骨灰。此外，人造骨灰还使用于铸造非铁金属的脱模剂，如铜。

Bone ash 骨灰Bone ash is a white material produced by the calcination of bones. Typical bone ash consists of about 55.82% calcium oxide, 42.39% phosphorus pentoxide, and 1.79% water. The exact composition of these compounds varies upon the type of bones being used, but generally the formula for bone ash is: Ca5(OH)(PO4)3. Bone ash usually has a density around 3.10 g/mL and a melting point of 1670 °C (3038 °F). Most bones retain their cellular structure through calcination. |
