FOUNDRY

Foundry Grade Chromite sand is a complex compound of various elements. The main elements Chromium as Cr2O3, Aluminium as Al2O3, Silica as SiO2, Magnesium oxide as MgO. It is a lustrous, brittle, hard metal. Its colour is silver-grey and can be highly polished.

It does not tarnish in air, when heated it burns and forms the green chromic oxide.

 

Chromium is unstable in oxygen; it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal.

 

Foundry grade chromite sand is used for its unique properties, high thermal conductivity, heat resistant, low heat dilating and a cost-effective way to produce and use in some of the below applications:

  • specially treated moulds

  • quality castings

  • metal casting

  • automotive castings

  • alloys such as stainless steel

  • chrome plating

  • Metal ceramics

  • Is used impart corrosion resistance and a shiny finish; as dyes and paints, its salts colour

    glass an emerald green

  • Is used to produce synthetic rubies;

  • as a catalyst in dyeing and in the tanning of leather;

  • to make moulds for the firing of bricks.

  • Chromium (IV) oxide (CrO2) is used to manufacture magnetic tape
