Chromite flour 75 μm （200mesh） is a superior refractory mineral for foundry coating and glass & ceramic pigment. It has the following properties

Foundry chromite sand has become a commonly used foundry sand in the fields of machinery and equipment, railway parts, etc. due to its excellent refractory temperature, resistance to steel sand erosion, anti-sticking sand, strong thermal conductivity, and high cost performance. The chromium content of chromite sand for foundry is not less than 46%, and the silicon content is not more than 1%.

Chrome ore foundry sand AFS 45/55 (particle size of about 0.25-0.35mm) is used as casting sand for railway turnout accessories. With its unique physical and chemical properties, it has excellent performance in high temperature stability and resistance to metal penetration.

Chrome powder 325mesh is fine chromite flour with 97% granular smaller than 45um.  By milling 46% raw chrome ore sand would get Chrome powder with Cr2O3 45-46%.

Recently, 500 Tons of foundry chromite sand AFS45-50 are prepared. SGS make the inspection before delivery.

The chromium materials used to make magnesia-chromite bricks are natural chromite grain and chromite powder with a chromium content of more than 46%. Chromite ore powder has the following performance advantages:
