Non-calcined diatomaceous earth, also referred to as natural diatomaceous earth, can be used in conjunction with diatomite heat insulating bricks to build high temperature resistant calcining furnaces. Not only is it used as the base material of heat insulating materials and refractory materials, but it is also used as the fillers between insulating layers.
Xinghui's non-calcined diatomaceous earth consists of SiO2, Fe2O3, Al2O3 and other chemical compositions. The service temperature of the natural diatomite is up to 800℃, and its volume density ranges from 0.4 g/cm3 to 0.8 g/cm3.
