Clay lightweight insulating refractory bricks have the characteristics of low bulk density, low thermal conductivity, excellent insulation performance, and stable quality. They can be used as linings or insulation layers in various high- temperature kilns, reducing thermal energy loss, saving energy, and lightening the weight of thermal kilns.
