Refractory bricks used in glass melting pools are susceptible to corrosion from direct contact with molten glass. The liquid glass temperature can reach 1500°C, requiring refractory bricks with high corrosion resistance. Maintaining stability at the refractory-glass interface and preventing spalling are also important to avoid glass defects. Zhengzhou Sunrise Refractory is a manufacturer of refractory products for the glass industry, including fused cast bricks and mullite, zircon, and magnesia bricks.
