Lower Price Lightweight Lz 75 High Alumina Fireclay Brick for Coke Oven
Fuller earth price fireclay brick is also known as fire brick. It is made of local top grade fireclay materials under the high temperature according to the lasted national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity. Fire clay refractory brick has wide usage and the largest production. Its Al2O3 is generally more than 40%, Fe2O3 is less than 2.0 ~ 2.5%. Clay brick has weakly acidic at high temperature and has poor performance in resistance to alkaline and slag erosion, but it increases with the increase of Al2O3 content. Fulle
