Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould 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.
In steel production, chrome ore sand /cr2o3 chromite is used as well filler for protection of the sliding gate in large steel holding ladles.
When ground to a fine flour, cr2o3 chromite/ceramsite foundry sand is used for the production of green glass beverage containers.
