Brown corundum grit sand is used in the crude steel refining process. Due to its high temperature strength, good fire resistance and corrosion resistance, brown corundum sand is often used as a refractory material. In addition, brown corundum alumina sand has strong slag resistance, so it can be used in kilns. It also works well in the manufacture of ceramics and other products.
