tan powder | [Potential Exposure]
Diatomaceous earth is 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.

If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical has been
inhaled, remove from exposure, begin rescue breathing
(using universal precautions, including resuscitation mask)
if breathing has stopped and CPR if heart action has
stopped. Transfer promptly to a medical facility. | [Shipping]

Silica, amorphous is a noncombustible solid. Generally unreactive chemically. Incompatible with fluorine, oxygen difluoride, chlorine trifluoride. Soluble in molten alkalis and reacts with most metallic oxides at high temperature. | [Waste Disposal]
Sanitary landfill. | [Uses]
Chemically,
diatomaceous earth is mostly amorphous silicon dioxide,
accompanied by mineral salts, with large surface area.
Its use as an insecticide dust is based on its capability to
absorb moisture, oils, and waxes (48). | [Definition]
Diatomite: A whitish powdered
mineral consisting mainly of silica (silicon(
IV) oxide) derived from the shells of
diatoms. It is used to make fireproof cements
and as an absorbent in the manufacture
of DYNAMITE. | [General Description]
Celpure? P65 (Diatomaceous earth, DE) is natural amorphous silica formed from the fossilized skeletons of diatoms. It is extracted, crushed, dried and calcined with or without flux material. DE is widely used as filler in construction materials, paints and as an anti-caking agent for agricultural chemicals. It has high water and oil absorption ability. The potential toxicity of different samples of DE has been assessed. DE is also employed as an adsorbent for column chromatography. | [Agricultural Uses]
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. | [Trade name]

| Questions And Answer | Back Directory | [Description]
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.
