Bone ash, a material steeped in history yet vital in modern manufacturing, owes its utility to a unique set of chemical properties. Derived from the calcination of animal bones, this white, powdery substance is a rich source of calcium phosphate, with its precise composition often influenced by the original bone material. Understanding these chemical characteristics is fundamental for procurement managers and formulators seeking to leverage bone ash effectively. As a leading manufacturer and supplier, we specialize in providing calcined bone ash that delivers consistent chemical performance for diverse industrial applications.

Chemical Composition and Key Properties

The core chemical makeup of bone ash typically includes calcium oxide (CaO) and phosphorus pentoxide (P2O5), often presented as calcium phosphates like tricalcium phosphate (Ca3(PO4)2) or hydroxyapatite (Ca5(OH)(PO4)3). During calcination at temperatures around 1100-1300°C, organic matter is removed, leaving behind a stable, inert inorganic material. This process preserves the porous cellular structure of the bone, contributing to its unique physical properties. Key characteristics include its high melting point, excellent heat transfer resistance, and its role as a source of calcium and phosphate. These properties make it an ideal additive for applications where specific chemical interactions or physical enhancements are required.

Benefits in Ceramics and Industrial Formulations

In the ceramics industry, bone ash is prized for its dual role as a flux and an opacifier. Its calcium content acts as a flux, lowering the melting point of glazes and clay bodies, thereby reducing firing temperatures and energy consumption. This fluxing action also contributes to the translucency characteristic of bone china. For formulators seeking to buy bone ash for glaze applications, its ability to create subtle opalescent effects or contribute to matte textures is highly valued. Beyond ceramics, its chemical stability and mineral content make it useful in other sectors. As a water treatment chemical, it can aid in phosphate removal or act as a clarifying agent. In coatings and plastics, it can serve as a functional filler, influencing properties such as hardness, opacity, or flame resistance.
