Bone ash

Bone ash (CAS 68439-86-1), also supplied under the designations HA 216 and Bone Ash 325, is a calcium phosphate-rich mineral derived from calcined animal bones. It functions as a stabilizer and mineral source across food, pharmaceutical, and agricultural applications.

In food manufacturing, bone ash supplies bioavailable calcium and phosphorus for fortified products including infant formula, dairy analogs, and nutritional supplements. Feed producers incorporate it as a mineral supplement to support livestock bone development.

This material helps meet nutritional specifications in compound feed formulations. Pharmaceutical manufacturers use it as an excipient and mineral carrier in tablet and capsule production where controlled calcium phosphate content is required.

In agriculture, it is applied as a slow-release phosphate fertilizer, delivering phosphorus to soil in a form accessible to crops over extended growing cycles. This ensures long-term nutrient availability for various plant species.

Bone ash is supplied as a fine white powder, with mesh grades such as 325 mesh available for applications requiring consistent particle size distribution. This consistency is vital for industrial and manufacturing processes.

Standard grades include food-grade and feed-grade specifications, with some material conforming to FCC requirements. Technical-grade material is available for agricultural and industrial use depending on the specific needs.
