Foundry chromite ore sand is a special sand for foundry. It is a natural spinel dominated by chromite sand from South Africa. After crushing, grinding and sieving in our factory in China, it is divided into prescribed grain size, and is suitable for sand for mounding (core-making). Chromium ore sand can be divided into two grades according to chemical composition, first grade Cr2O3 (> 45%) and second grade Cr2O3 (> 35%).


  1. Heated Volume Stability
  2. High thermal conductivity
  3. Strong alkali resistance
  4. Solid phase sintering, non-sticking sand


  1. 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 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.
  2. 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.
  3. Chromite Sand in the glass industry
    When ground to a fine flour, Chromite Sand is used as colorant for the production of green glass beverage containers.
