Chrome Ore Foundry Sand Chromite sand 46%min Cr2O3
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.
It is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa. The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.
Characteristics
1. Chromite sand with Heated Volume Stability
2. Chromite sand with High thermal conductivity
3. Chromite sand with Strong alkali resistance
4. Chromite sand with Solid phase sintering, non-sticking sand
