About Chromite Sand
Chromite is a crystalline mineral composed primarily of FeO and Cr₂O₃ compounds. It can be represented by the chemical formula of FeCr₂O₄. It is an oxide mineral belonging to the spinel group.
Key Properties of Chromite Sand
Chromite Sand has good thermal conductivity and is resistant to thermal shock. It also has excellent resistance to metal penetration or burn on. Resistant to slag attack and high dimensional stability.
Uses
Used in the foundry industry for the manufacture of moulds and cores. Chromite Sand is applicable to all types of steels and very appropriate for Chrome Steel, Chrome-Nickel and Manganese Steel. Also used in the refractory sector to produce various chemicals and as a pigment.
