Chromite sand originating from South Africa is a benchmark product in the global foundry industry. it is a naturally occurring spinel consisting primarily of the oxides of chrome and iron

Chromite sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production. Chromite Flour Core Properties Melting point: ~2180℃, high refractoriness High thermal conductivity, good chemical inertness against molten steel/iron Low thermal expansion,

chromite sand superior thermal stability, inertness, and durability justify its use in critical industrial processes

 The use of Chromite Flour 325 mesh as a foundry coating (refractory coating) is a highly specialized and critical application, primarily in the production of high-quality steel and manganese steel castings. PHYSICAL PROPERTIES(TYPICAL)  AVERAGE CHEMICAL COMPOSITION(TYPICAL) PH 7-9 Cr2O3 ≥46.0% Color Black SiO2   ≤1.0% Acid Amount ≤2m Fe2O3 ≤28.5% Soil% ≤0.1 CaO ≤0.30% Bulk Density 2.5-3.0g/cm3 MgO

Chromite sand high melting point, thermal stability, and resistance to metal penetration make it ideal for demanding casting processes, such as engine blocks, cylinder heads, brake components, and transmission parts.

Chromite powder is fine ground powder processed from natural chromite ore, mainly composed of iron chromium oxide. It features high refractoriness, low thermal expansion, excellent chemical stability and strong chilling effect, widely used in foundry and refractory industries.
