Bone Ash Supplier in Malaysia
- Also known as
- Calcined Bone
Bone ash supplier for metallurgical, ceramic, feed and fertiliser buyers in Malaysia. Bone ash is calcined bone, consisting mainly of calcium phosphate in the form of hydroxyapatite, and it is identified by CAS 68439-86-1.
Commercial material is a white to off-white powder or granules. Grades separate assay quality for cupels, ceramic quality for bone china, and feed and fertiliser quality, and they differ mainly in fineness and phosphate content.
Precious-metal assayers use it to make the porous cupels that separate lead and base metals during fire assay. Ceramic makers rely on it for bone china bodies, while feed and fertiliser producers use it as a phosphorus and calcium source.

| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Assay-grade bone ash | fine white to off-white powder | — | Cupel material for fire assay of precious metals, where a porous, absorbent calcined bone body is needed to draw off lead and base metals. | Bag packing; format confirmed with the quotation. |
| Ceramic-grade bone ash | fine white to off-white powder | — | Body material for bone china and speciality ceramics, valued for the translucency and strength its calcium phosphate gives the fired ware. | Bag packing; format confirmed with the quotation. |
| Feed and fertiliser-grade bone ash | white to off-white powder or granules | — | Phosphorus and calcium source in animal feed premixes and fertiliser blends, quoted against the nutrient profile required. | Bag or jumbo bag; format confirmed with the quotation. |

Common questions about bone ash
What is bone ash?
Bone ash is calcined bone, consisting mainly of calcium phosphate in the form of hydroxyapatite. It is supplied as a white to off-white powder or granules in assay, ceramic, feed and fertiliser grades.
Which grade is used for cupels?
Assay-grade bone ash is ground to the fineness cupel making needs, so it forms the porous bodies used in fire assay of gold and silver. Tell us your cupel process and we will confirm the specification.
Is it suitable for bone china?
Ceramic-grade bone ash is the calcium phosphate source used in bone china bodies. Send your fired-ware requirements and we will quote the matching grade.
How is bone ash packed?
Powder grades are usually bagged, with jumbo bags for larger feed and fertiliser orders. The pack format is confirmed with the quotation.
