This is a porous, low-density, sedimentary rock formed by the accumulation and compaction of diatoms which may comprise 90% or more of the dry weight of the rock. The physical properties of diatomite have led to its use in many commercial applications, the most common being for the filtration of liquids or as a filler, for example, in paints.

Diatomite was defined as a "pale coloured, soft, light-weight rock composed principally of the silica microfossils" (Inglethorpe, Reference Inglethorpe 1993, p. 1). A diatomite of high SiO 2 purity (ranging from 80 to 99 wt% of biogenic SiO 2 ) is now commonly used in scientific research as a reference material in isotope geochemistry for ...
Aug 29, 2018 - Diatomite and diatomaceous earth are sedimentary rock products that are used for filter media, absorbents, fillers, abrasives, and many other purposes.
Motivated by the hierarchical micro and nanoscale features in terms of porosity of diatomite, the production of ceramic-graded porous foams with tailored porosity, obtained by using it as raw ...
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. The sediments are fine-grained, highly siliceous, and consist primarily of amorphous ...

The porous nature gives it many useful properties. Diatomaceous earth is widely used in industry for many different applications. Pure diatomite is white as this sample from Armenia. Its width is 7 cm. Diatomite is friable and fragile very light-weight rock.
Porous or permeable rocks allow liquids to pass through them while non-porous or impermeable rocks do not. On either side of the rock containing oil, there is a non-porous rock which does not allow liquids to pass through it. To get the oil out to the surface, the rocks are drilled using s until the oil is reached.

Diatomite is a kind of biogenic siliceous sediment, which is mainly composed of the ancient remains of diatoms. SiO2 content of diatomite is usually more than 80%, the most content can reach to 94%. Diatomaceous mineral compositions are mainly opal and its variants, followed by clay minerals, such as water mica, kaolinite and mineral debris.
Diatomite is a highly porous silica-rich material mainly composed of diatom shells. Even though the shells are porous themselves, the remarkably high porosity of diatomite is due to the open spaces present between the diatom shells composing the rock. The porous structure of diatomite makes it a poor conductor of heat and a good insulator.

Diatomite is a biologically occurring sedimentary rock whose main component is silica. Previous studies showed that diatomite and its derivatives have good sorption properties for heavy metal ions, such as Cu 2+, Pb 2+, Cr 3+ and Zn 2+, because of its unique porous framework [10,11,12]. Natural rocks usually have weak sorption ability for ...
