Product Introduction
Directly combined with magnesium chromium bricks, high-purity magnesium sand and chromium concentrate are used as the main raw materials, and special magnesium chromium composite spinel is added. It is formed under high pressure and sintered at high temperature. This product has few impurities, and the glass phase is concentrated in the triangular region of the crystal. The crystal phase is directly combined with the crystal phase, and has the characteristics of low porosity, high compressive strength, good wear resistance, corrosion resistance, and peeling resistance. In 2009, it was granted a national invention patent (patent number ZL20071 0189924.0).
