Zircon refractory bricks are made of high-quality raw materials, composite ultra-fine powder, and special additives through high-pressure forming and high-temperature sintering. They have the advantages of strong anti-glass erosion and anti-penetration ability, excellent thermal shock stability, and high-temperature creep resistance. They are mainly used in the molten pool and superstructure of glass furnaces.
