Iron Chromate flour 325mesh
Iron chromate flour 325mesh is a typical inorganic mineral pigment for green glass bottle, glass container and ceramic glaze. It can resist high temperature of glass & ceramic sintering. Chromate flour 325mesh is a fine-grained black particle. The approximate chemical composition is described by the chemical formula FeCr2O4. In industrial production, it is obtained by grinding and further dispersing the fine particles of chromite ore.
Features of Iron Chromate flour 325mesh:
- High refractory temperature, good high-temperature stability, good performance at 1800 ℃, and does not affect the firing of glass products.
- Good heat shock resistance, corrosion-resistant glass and slag.
- The content of Cr2O3 is higher than 46%.
- The particle size is uniform and delicate, with strict control over particle size.
