Diatomaceous earth: Diatomaceous earth kills and repels insects, including
bed bugs, fleas, cockroaches, and carpet beetles, by
dehydrating them, rather than chemically poisoning them,
and has been used since early times. It is also used as a filtering
agent and as a filler in construction materials, pesticides,
paints, and varnishes. The calcined version (which
has been heat treated) is the most dangerous and contains
crystallized silica, and should be handled as silica.

Celite mainly refers to diatomaceous earth. It is a naturally occurring, soft, siliceous sedimentary rock. It is consists of fossilized remains of a type of hard-shelled algae, diatoms. It contains mostly silica (80% to 90%) as well as small amount of alumina and iron oxide. Celite has various applications. It can be supplied to the explosive to make them more stable for transport. It can also be used as a filtration acid as well as abrasive to be used in toothpaste, metal polishes as well as some facial scrubs. It can also be used as an insecticide for pest control. Its thermal properties make it be used as the barrier material in some fire resistant safes. It can also be used as a liquid absorbent, matting agent of coatings, catalyst support, activator in blood clotting studies, stabilizing component of dynamites, and a thermal insulator. It is also useful in construction.
