Diatomite insulating brick


Diatomite brick

More details


Diatomite insulating brick is produced from high quality diatomite raw material. Clay need to be added into the raw material in order to get enough strength. In order to improve the insulation properties of diatomaceous insulation brick, combustible ingredients are mixed in, such as asbestos fibers, sawdust and etc. After drying , the diatomite insulation brick is fired in the temperature between 900 to 1000 C.
