Chromite is composed of chromium, iron and oxygen. It 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.
Chromite sand characterise:
- high melting point
- excellent thermal stability
- high density
- medium Mohs hardness of 5.5

MAIN APPLICATIONS:
Chromite Sand in the foundry industry
Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould,and chromite sand used in the foundry industry as a moulding sand
making sand. Its high thermal conductivity gives it good chilling properties, low thermal expansion gives rise to good dimensional stability. Its basicity being close to neutral allows the use of a wide range of resin bonding systems and inorganic binders, it has a high refractoriness and a broad sieve distribution.
Chromite Sand in the steel industry
In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles.
Chromite Sand in the glass industry
When ground to a fine flour, Chromite Sand is used for the production of green glass beverage containers.
