Diatomaceous earth is a soft, siliceous sedimentary rock containing the fossilized skeletal remains of diatoms. ... mainly in the form of amorphous silicon dioxide but with some crystalline silica. Silica is dangerous when inhaled, causing lung disease in workers exposed to silica dust. Silicosis is the most common occupational disease worldwide.

Whenever we mine our planet, we uncover these remains as a thick whitened siliceous powder. Food-grade diatomaceous earth offers important health benefits, particularly related that it consists of roughly 85% amorphous silica.

Silica, Amorphous Diatomaceous Earthis a grey, odorless powder. It is used as a filtering agent and as a filter in construction materials, pesticides, paints, and varnishes. REASON FOR CITATION *Silica, Amorphous Diatomaceous Earthis on the Hazardous Substance List because it is regulated by OSHA and cited by NIOSH and IARC.
Details 
Amorphous silica (diatomaceous earth) is composed of the skeletons of prehistoric plants known as diatoms. These skeletons are largely noncrystalline, although diatomaceous earth can contain varying amounts of crystalline quartz, which has led, in the opinion of the ACGIH (1986/Ex. 1-3, p. 520), to conflicting results in studies of the ...

F. Rabel, in Encyclopedia of Separation Science, 2000 Kieselguhr (Diatomaceous Earth) Kieselguhr or diatomaceous earth is an amorphous silica of fossil origin. Once mined and carefully cleaned, it can be used as a support for TLC. It has a very wide pore size, and very low surface activity compared to silica gel and other TLC sorbents.

Food-grade diatomaceous earth offers important health benefits, particularly related that it consists of roughly 85% amorphous silica. Previously, humans could consume enough silica in foods, but as modern hybrid meals and toxic soil grew to become real, studies claim that no more than 1/3 silica that people require is contained in our fruits ...

Most diatomaceous earth is made of amorphous silicon dioxide. However, it can contain very low levels of crystalline silicon dioxide. The first pesticide products containing silicon dioxide (diatomaceous earth) were registered in 1960 to kill insects and mites.

Diatomaceous earth (/ ˌ d aɪ ə t ə ˈ m eɪ ʃ ə s /), diatomite (/ d aɪ ˈ æ t ə m aɪ t /), or kieselgur/kieselguhr is a naturally occurring, soft, siliceous sedimentary rock that can be crumbled into a fine white to off-white powder. It has a particle size ranging from more than 3 μm to less than 1 mm, but typically 10 to 200 μm. Depending on the granularity, this powder can have ...

Details 
Silicon dioxide (Si02 or amorphous silica) is the main element in diatomaceous earth however all diatomaceous earth products, in their natural (raw) state, typically contain 20-35% addition elements other than silica. Color and formulation also vary between deposits and can be affected by the manufacturing processes.
