Profile: Hebei Xuankun Refractory Material Technology and Development Co., Ltd. specializes in providing silica bricks. Silica bricks for glass furnace belong to silicon refractory products used in high temperature glass as refractory lining of the kiln. Silica brick for glass kiln has the characteristics of purity, density, strength and refractoriness, it has accurate size tolerance, pure color and luster appearance. The higher SiO2 content, the higher temperature silica bricks resist. Glass kiln silica brick has high temperature and volume stability, no pollution to glass liquid, chemical corrosion resistance, small bulk density, and can reduce the weight of furnace body.
