Laurel Zirconia refractory bricks are made of natural zircon sand as raw material. It has high resistance to slag. It has become an important material in various industrial fields because of its low thermal expansion, low thermal conductivity as the temperature increases, high softening point of the load, high abrasion strength and good thermal shock stability. With the development of continuous casting and vacuum degassing technology in the metallurgical industry, zircon bricks are more and more widely used.
