Chromite flour 45um mineral Inorganic green pigment
Chromite flour 45um is a mineral inorganic pigment for green color. Though the apperance of chromite flour is red-black, it works well for green bottle, Olive color wine bottle as colorant. By fine milling process from Iron chromite sand, we can make passing rate higher than 98% of 325 sieve mesh. 98% particles of 325# chrome flour are smaller than 45um. So the chromite flour 45um can distribute in the glass evenly and avoid black stains.
Features of Chromite flour 45um mineral Inorganic green pigment:
- 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.
