What Is Chromite

Specifications

Feature:

1. Heated Volume Stability

2. High thermal conductivity

3. Strong alkali resistance

4. Solid phase sintering, non-sticking sand

THE ADVANTAGE OF CHROMITE SAND

Comparing with silica sand, chromite sand can avoid most sand stick on the casting, therefore it can also save cost to make surface treatment. Moreover, chromite can be recycle used for several times upon to different technology.

Over all the chromite ore in the world, the one from South Africa are of the best quality level. So HAIXU Abrasive import original chromite ore from there and refine it to better purity to 46% Cr2O3.
