DESCRIPTION: 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 has the following properties in terms of performance: 》》The color of chromite flour 325 mesh. Chromium element is a commonly used raw material for green pigments and colorants in industry. Chromite flour contains 46% chromium oxide. Although it looks black brown or black green, it can produce an Emerald Green or Georgia Green

chromium ore, also known as chromite, is also used in the refractory and metallurgical industries. Its resistance to fire of up to 1900 °C, good gas permeability and low thermal expansion combined with good thermal conductivity make this raw material an effective barrier to molten metal compared to other moulding sands. Furthermore, in contrast to

chromite powder, chrome flour 325, and chromite flour, it is an inorganic compound that is used as a pigment and as a vital component in some of the highest performing refractory materials. Its chemical composition is Cr2O3. Chromite is the sole naturally occurring ore of chromium, occurs with iron oxide, and It has a melting
