What is bone ash?

Bone ash, also known as calcium phosphate, is a white, odorless powder that is produced by burning animal bones at high temperatures until they are completely calcined. It is primarily composed of calcium oxide and phosphorus pentoxide, along with trace amounts of other minerals.

Bone ash has a variety of industrial uses, including as a fertilizer, in the production of ceramics and glass, and as a source of calcium and phosphorus in animal feed. It is also used in the manufacturing of bone china and as a flux in metallurgy.

In addition to its industrial applications, bone ash has been used historically in traditional medicine as a calcium and phosphorus supplement. However, due to concerns about its potential for heavy metal contamination, its use for this purpose is limited.

Overall, bone ash is a versatile substance with a wide range of practical applications in various industries.
