Chromite sand is a high-performance specialty foundry sand mainly composed of FeCr₂O₄ (chromium iron oxide). It is widely used in steel casting, alloy steel and high-temperature alloy casting due to its high refractoriness, high thermal conductivity, low thermal expansion and excellent anti‑penetration properties. Cr2O3 SiO2 FeO CaO MgO Al2O3 P S Cr/Fe ≥46.0 ≤1.0% ≤28.5%

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 sand (FeCr₂O₄) is a high‑performance specialty foundry sand, widely used for molds/cores in steel, iron, and high‑alloy casting, valued for high refractoriness, low expansion, high thermal conductivity, and excellent anti‑penetration.

Chromite sand is a high‑refractoriness, low‑expansion, high‑thermal‑conductivity mineral sand widely used across foundry, refractory, metallurgy, glass, ceramics, construction, and friction materials.

325-mesh chromite flour is a premium, performance-enhancing material used primarily as a refractory coating in steel foundries to achieve superior casting surface quality and as a fine aggregate in advanced refractory bricks and monolithics for high-temperature industrial furnaces.

Chromite flour is a specialized, problem-solving refractory material. Its core application is to serve as a highly stable, chemically inert, and thermally conductive face-coat material in the investment casting of reactive high-temperature alloys and as a high-performance mold wash in sand casting of demanding steels.
