Chromium ore powder 325#mesh
The raw material of our chromium ore powder 325# is from South Africa. It is a natural spinel with special powder for foundry/coatings. Its main chemical components are Cr2O3 (Cr2O3 ≥ 46.0%), and chromium ore powder is stable with heating volume and high thermal conductivity.
Application: Used in high duty grey iron and steel foundries as core and mould making sand, in steel production it is used as filter. Used for production of glass containers.
