High Alumina Brick & High Aluminum Castable Difference 1.Difference between high alumina bricks and high alumina castables is that one is a high alumina refractory brick made by high temperature sintering, and the other is a bulk material made of high alumina aggregate, powder and binder. 2.Appearance shape, high alumina brick is sintered refractory brick with fixed shape and size, high aluminum castable is bulk material, no fixed shape. 3.Construction method, refractory bricks are constructed by masonry, and refractory castables are casted. 4. The price of high aluminum bricks is higher than the high aluminum refractory castables. High Alumina Bricks Definition High alumina brick refers to alumina with a content of more than 48% and less than 90%. It is made of refractory brick made of high alumina bauxite or sillimanite. high alumina refractory brick is usually divided into three according to the Al2O3 content in the product: The Al2O3 content of the ...

JM28 Insulation Brick Introduc tion   J M28 Insulation Bricks  are made from high purity  refractory  materials by unique  technology , so they have a lot of advantages such as stable volume, excellent thermal stability, high intensity, and low thermal conductivity. They are an ideal kind of energy-conserving products, which can be widely used as linings or as thermal preservations layes in various industrial furnaces and kilns in metallurgical industry, ceramic industry, chemical industry and machinery industry.   Application of JM28 Insulation Brick   Glass industries iron & steel industries .
