1.0 Diatomite and Diatomaceous Earth (Kieselguhr)

Thermal processing or calcination with or without flux is a common process in diatomaceous earth production. The thermal treatment of diatomite is a sintering or agglomeration process achieved through partial melting. Calcination not only dehydrates the amorphous silica but initiates conversion of Opal – A to cristobalite (40-60%).

Diatomite - North America

Processing of the diatomite ore usually fractures the individual diatom skeletons. Without additional processing, the resulting powder, composed of mainly broken diatom pieces, is referred to as “natural” diatomaceous earth. Such powders are limited in their use because the particle sizes are too small for the majority of applications.
