Chromite powder is a natural inorganic mineral powder. It is a composite mineral primarily composed of FeO and Cr₂O₃. The quality of chromite powder depends on the grade of chromite sand used. Our factory selects African chromite ore with 46-50% and 40-42% content as raw materials, utilizing advanced grinding equipment and preparation methods to produce chromite powder suitable for the pigment and casting metallurgy industries.
Iron Chromite flour is a natural inorganic mineral powder. It is a composite mineral mainly composed of FeO and Cr2O3. The quality of chromite flour comes from the quality of chromite sand of different grades. Our factory uses African chromite with a content of 46-50% and 40-42% as raw materials, and adopts advanced grinding equipment and preparation methods to obtain chromite flour suitable for pigments and casting metallurgy fields.
Characteristics of chromite powder:
1. High refractory temperature, excellent high-temperature stability, and stable physicochemical properties at 1800°C.
2. Good thermal shock resistance, corrosion-resistant to glass and slag.
3. Good thermal conductivity, low thermal expansion rate.
4. The chromium oxide content is divided into two types: 46% and 41%.
5. The particle size is uniform and fine, with strict control over particle size distribution.
6. Low cost, high cost-effectiveness.
7. High specific gravity, excellent wear resistance.
