Diatomaceous Earth: Calcined vs. Non-Calcined - Absorbent ...

Jan 17, 2019  Calcined diatomaceous earth has been treated at a temperature above 1000 ºC. The purpose of this is to further harden the exoskeletons of the diatoms in order to create a better filtering agent. This process causes the amorphous silica that makes up the exoskeleton of the diatom to turn in to crystalline silica. This is a benefit if the ...
