Product Details
Corundum Brick have stable quality and excellent durability. These products are made mainly of calcined alumina, mullite, corundum of high purity. These bricks have low porosity, excellent hot strength and creep resistance, and good volume stability at high temperature.Jucos Corundum Brick have been developed to meet the most demanding specifications for various industrial applications.
The products have a compact structure, high compressive strength, and high temperature resistance (> 2200 “C). It has good thermal shock stability, is resistant to acid and alkaline gases, and is not affected by reducing gases such as H2 and Co.High-purity corundum products are widely used in oil or gas gasifiers, ethylene gasifiers, ammonia decomposition furnaces in petrochemical industries, carbon black reactors in the chemical industry, refractory materials and high-temperature kilns in the ceramic industry.
