Lightweight clay bricks are refractory materials made from clay and lightweight additives, such as perlite, vermiculite, or sawdust. They have a low bulk density and high porosity, making them lightweight and thermally efficient. They are widely used for insulation and construction purposes in various industries, as well as in building construction.
Lightweight clay brick is a high-temperature heat-insulating refractory material. It uses refractory clay clinker as a raw material and plastic clay as a binder, adding an appropriate amount of combustibles or foaming agents. It is pressed into shape by a brick press and then sintered. It has high strength, good thermal shock stability, slight change of burning line, small thermal conductivity, good thermal insulation performance, etc. It is widely used in thermal equipment such as metallurgy, machinery, ceramics, the chemical industry, industrial kiln lining, and thermal insulation layers.
