chromite powder, chrome flour 325, and chromite flour, it is an inorganic compound  used as a pigment Its chemical composition is Cr2O3. Chromite is the sole naturally occurring ore of chromium, occurs with iron oxide, and It has a melting point of 2,040 °C. It is referred to as being “almost chemically inert”(1), lending itself

Chromite is composed of chromium, iron and oxygen (chemical formula FeCr2O4). It is an oxide mineral belonging to the spinel group.  chromite sand is used in the foundry industry as a moulding sand, as a pigment in ceramic glazes and container glass, and as an additive in brake lining applications.  CHEMICAL COMPOSITION Cr2O3 ≥46.0% SiO2 ≤1.0% FeO ≤26.5% CaO ≤0.3%
