diatomaceous earth, diatomite, kieselguhr(noun)
a light soil consisting of siliceous diatom remains and often used as a filtering material
a deposit of fine, usually white, siliceous material, composed mainly of the shells of the microscopic plants called diatoms; also called infusorial earth, kieselguhr, and diatomite. It is used in polishing powder, and in the manufacture of dynamite.
A light soil consisting of siliceous diatom remains and often used as a filtering material or microabrasive.
Diatomaceous earth also known as D.E., diatomite, or kieselgur/kieselguhr, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 micrometre to more than 1 millimeter, but typically 10 to 200 micrometres. Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder, and is very light as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina and 0.5 to 2% iron oxide. Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, mild abrasive in products including toothpaste, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics and rubber, anti-block in plastic films, porous support for chemical catalysts, cat litter, activator in blood clotting studies, a stabilizing component of dynamite, and a thermal insulator.
U.S. National Library of Medicine
A form of SILICON DIOXIDE composed of skeletons of prehistoric aquatic plants which is used for its ABSORPTION quality, taking up 1.5-4 times its weight in water. The microscopic sharp edges are useful for insect control but can also be an inhalation hazard. It has been used in baked goods and animal feed. Kieselguhr is German for flint + earthy sediment.
