These properties make it useful as a filter media, an absorbent, and as a lightweight filler for rubber, paint, and plastics. When diatomite is crushed into a powder, it is usually called "diatomaceous earth," or D.E. Diatoms are microscopic, single-celled algae that live in marine or fresh water. They produce hard parts made of silicon dioxide.

The diatomite purification in HCl and the diatomite calcination (Goren et al., 2002; Khraisheh et al., 2005) have been applied to make diatomite more inert for using the treated diatomite as filter support. In these processes, the disappearance of the OH groups on the diatomite surface has a detrimental effect on the surface area.
