Product Description Product : Bone Ash for Silver & Brass Casting - Heat Resistant Coating MaterialProduct Description:Bone Ash is a white, high-purity material made by calcining (burning) animal bones at high temperatures in the presence of air. This process removes organic matter and leaves behind primarily calcium phosphate (Ca3(PO4)2). Bone ash is valued for its chemical stability, high melting point, and excellent refractory properties, making it suitable for multiple industrial applications.

Mold Coating / Release AgentBone ash is applied as a powder coating or slurry on the surface of molds used in casting.It forms a non-stick, heat-resistant barrier between the molten metal and the mold.Prevents the molten metal from adhering to the mold, ensuring a clean release and a smooth casting surface.2. Prevents Oxidation & ReactionBone ash is chemically stable and doesn't react with molten metals.It acts as a protective layer, preventing unwanted reactions or oxidation during pouring and solidification.3. Thermal InsulationBone ash provides excellent insulation, helping to maintain temperature inside molds and avoid premature cooling.This is particularly important in precious metal refining, where uniform temperature is critical.4. Fluxing (Less Common)In some cases, bone ash is used as a minor component in fluxes, aiding in impurity separation during metal refining.
