Chromite-Grey-Green Powder for pigment in glass and ceramic applications
Chromite is a grey-green powder typically used as a pigment in glass, ceramic applications amd for suspension product.
The suspension product made bu our chromite powder was developed to eliminate the handling of dusty powders in the working environment and to allow for greater control of addition rates and reduce waste.

Characteristics of Chromite-Grey-Green Powder for pigment in glass and ceramic applications
- Accurate fineness, with a sieve pass rate of over 97%, and can also achieve full pass according to customer requirements.
- Low moisture content, dry without clumping.
- High refractory temperature. Chromite sand is originally a good casting refractory material, with a melting point of 2180 degrees and a sintering temperature greater than 1850 degrees.
- Superior thermal conductivity. Compared to zircon powder, chromite powder has stronger thermal conductivity.
- Low coefficient of thermal expansion. Although the thermal expansion coefficient of chromite flour is slightly higher than that of zircon powder, it is much smaller than that of silica sand. In terms of the low cost of chromite flour, it has a high cost-effectiveness. It can prevent deformation of castings.
