This paper examines the calcination and filtration characteristics of diatomite.For this purpose, diatomite ore was calcined at 1000 °C in order to improve the material characteristics for use in filtration. The physical, chemical, thermal and micro-structural features of the raw and the calcined diatomites were then determined to …

Diatomite is a soft, friable and very fine-grained siliceous sedimentary rock composed of the remains of fossilized diatoms. Chalky to the touch and often light in color, diatomite can be white if pure, but more commonly it is buff to gray in situ, or sometimes black. Because of its low density and high porosity, it is extremely lightweight ...

Approximately 60% of diatomite is used in filtration products. The remaining 40% is used in absorbents, fillers, lightweight aggregates, and other applications. A small amount, less …

This study investigates the ability of diatomite earth&carbon (DE&C) as an adsorbent to removal crystal violet (CV) from aqueous solutions. Fourier transform infrared spectroscopy results indicate the importance of functional groups during the adsorption of CV. The obtained N2 adsorption-desorption isotherm values accord with well IUPAC type II.

Diatomite, a soft, porous, fine-grained, lightweight, siliceous sedimentary rock, is produced by the accumulation and compaction of diatom (Class Bacillariophyceae) remains. The cell wall of living diatoms is impregnated with silica (amorphous hydrous, or opaline (SiO2.nH2O)), which preserves ornate and highly porous structures (Armbrust, 2009).
