The Main Classification Of Insulation Bricks

Usually divided into three types:

(1) Ordinary heat-insulating bricks, whose service temperature is below 1000℃, mainly include diatomaceous earth bricks, expanded razor stone bricks, expanded perlite bricks, etc., which are mostly used as heat insulation layers for thermal equipment.

(2) Refractory and heat-insulating bricks, whose service temperature is between 1000 and 1500°C, mainly include light clay bricks, light silica bricks, and light high alumina bricks.

(3) High-temperature insulation bricks, whose service temperature is above 1500℃, can be directly used as the lining of high-temperature kilns. They mainly include lightweight corundum bricks, hollow alumina sphere products and zirconia hollow sphere products.
