For professionals in the chemical and manufacturing industries, a thorough understanding of raw material composition and properties is fundamental to successful product development and consistent production. Bone ash, a widely used industrial chemical, is primarily valued for its calcium phosphate content and unique physical characteristics. As a leading supplier and manufacturer, we aim to provide clarity on the chemical composition and properties that make bone ash an indispensable material across various sectors.

Industrial bone ash is typically derived from animal bones, predominantly cattle, which are processed through calcination at high temperatures, often around 1000-1300°C. This thermal treatment effectively removes all organic matter, leaving behind a rich mineral residue. The primary chemical constituent of bone ash is calcium phosphate, with its exact composition varying slightly depending on the source bones and processing conditions. A common representation of its composition includes approximately 55.82% calcium oxide (CaO) and 42.39% phosphorus pentoxide (P2O5). Some sources cite its general formula as Ca5(OH)(PO4)3, or hydroxyapatite, which is the main mineral component of bone. The CAS number commonly associated with bone ash is 68439-86-1, though related compounds might have different identifiers.

Physically, bone ash typically presents as a fine white powder. Its properties are directly influenced by the calcination process. The preservation of the bone's cellular structure, even after heating, contributes to its unique behavior in applications like ceramics. Chemically inert and free from organic materials, it offers excellent thermal stability. Its density is typically around 3.10 g/mL, and it possesses a high melting point, often cited around 1670°C. These physical attributes make it a robust ingredient for high-temperature applications.

The significance of these properties is evident in its applications. In ceramics, the calcium phosphate acts as a flux, lowering firing temperatures and enhancing translucency, especially in bone china. In glazes, it can serve as an opacifier or flux. Its chemical inertness is beneficial in water treatment and as a component in certain industrial coatings.
