Iron Chromium Powder 45um 44um for ambor colorant
Alternative name: Chromite powder, Chromite flour, Iron chromite flour, Ferro Chromite flour, Iron Chrome flour, Iron chromium powder
Iron Chromium Powder 45um 44um for ambor colorant 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 Iron chromite flour:
- High refractory temperature, good high-temperature stability, and stable physical and chemical properties at 1800 ℃.
- Good heat shock resistance, corrosion-resistant glass and slag.
- Good thermal conductivity and low thermal expansion rate.
- Chromium oxide content is divided into two types: 46% and 41%.
- The particle size is uniform and delicate, with strict control over particle size.
- Low cost and high cost-effectiveness.
- High specific gravity and excellent wear resistance.
