Diatomite. The term diatomite is applied both geologically and commercially to the nearly pure sedimentary accumulation of diatom frustules—the microscopic skeletons of unicellular aquatic algae belonging to the class of golden brown algae, Bacillariophyceae.

called diatomite. Diatomite is a soft, very ﬁ ne grained sedimentary rock with a chalk-like appearance. These silica-rich rocks are very ﬁ nely porous and low in density—they will ﬂ oat on water until they become saturated. Diatomite is used principally as a ﬁ lter aid (for example, in the clariﬁ cation of wine

The diatomaceous earth or diatomite (German: Kieselgur; Italian: farina fossile), are found in the lake deposits of innumerable diatom shells: it forms a very porous mass, sometimes loose and floury, sometimes compact and claylike, always very light-white, grtey, or yellowish. Tripoli on the other hand is a marine sediment mainly com-

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be ...

Diatomite and Diatomaceous Earth - Geology

What is Diatomite? Diatomite 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.

On the Use of Sodium Chloride and Calcined Diatomite ...

Solid bricks manufactured out of clayey earth from a quarry near the city of Granada (Spain) were studied and compared with others to which two additives were added during the kneading of the raw material: Calcined diatomite sludge and sodium chloride. Samples with and without additives were fired at 800 °C, 950 °C, and 1100 °C. New mineral phases were formed in the bricks after firing.
