Features: 
Light weight brick 
High porosity. 
Good heat insulation. 
High compression strength. 
Low volume density. 
Bricks for general industryial kilns 
1. ISO***1 audited 
2. High quality with factor price 
Advantage: For the light weight brick, it will be created a lot of stomatal in the production process, so the bricks' contraction is bigger (about 9~*5%), and the three directions contraction is also not the same, and the bricks have large deformation in the process of drying and firing. So it is very difficult to control the demension. But we can manufacture the accurate dimension. 
Application: Electric furnace, blast furnace, cement kilns, Industrial furnaces
