1.Fire Clay Insulating Brick Description

The Al2O3 content of light clay refractory bricks is 30% to 46%. It is a lightweight refractory product, which is mainly composed of clay or light clinker. Usually, it can be made combustible by chemical or foam method, and finally, form a multi-hollow structure. The bulk density of commonly used lightweight clay bricks is 0.75~1.20g/cm3, the compressive strength is 2.0~5.9Mpa, and the thermal conductivity is 0.221~0.442W/m.k (1350°C).
