Unburned Magnestia-chromite brick
Unburned Mg-Cr brick is the product that made by using high-quality magnesia and chromium ore as raw material, phosphate binders for the molding in high pressure and low temperature processing. Compared with firing products, It has such advantages of simplified making procedures, compressive strength, stable thermal shock, and low cost.
