Diatomite and Diatomaceous Earth

PropertiesCharacteristicsEcologyFormationApplicationsUsesOther usesCultivationManagementPreventionTreatmentProductionCostDiatomite is a friable light-colored sedimentary rock that is mainly composed of the siliceous skeletal remains of diatoms. It is a very porous rock with a fine particle size and a low specific gravity. 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.

Diatomite Statistics and Information

Diatomite is a chalk-like, soft, friable, earthy, very fine-grained, siliceous sedimentary rock, usually light in color (white if pure, commonly buff to gray in situ, and rarely black). It is very finely porous, very low in density (floating on water at least until saturated), and essentially chemically inert in

What is Diatomite?

The properties which make diatomite valuable include low density, high porosity, high surface area, abrasiveness, insulating properties, inertness, absorptive capacity, brightness, and high silica content. Diatomite has a wide variety of uses, and is a component in hundreds of products, or vital to the manufacturing process of thousands more.

A sample of diatomaceous earth. Diatomaceous earth, also known as DE, TSS, diatomite, diahydro, kieselguhr, kieselgur and Celite, is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into a fine white to red powder or granulate. The powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity.
