[[File:Diatomaceous earth rock.jpg|thumb|300px|Raw piece of diatomite.]]<br />
'''Diatomaceous earth''' ('''D.E.''') more commonly known as '''diatomite''', '''kieselgur'''/'''kieselguhr''' or '''celite''', is a naturally occurring, soft and frangible siliceous sedimentary rock. Diatomaceous earth mainly consists of fossilized remains of diatoms, a type of hard-shelled algae, with other impurities such as metals (usually iron and calcium) and minute traces of organic matter.<br />
<br />
==Properties==<br />
===Chemical===<br />
Diatomaceous earth consists mostly of [[silicon dioxide]] and resists corrosion by acids.<br />
<br />
Heating diatomite between 800-1000 °C in a kiln will cause it to turn orange-red. <br />
<br />
===Physical===<br />
Diatomite is a white-ish light solid, with an abrasive feel, and highly porous. It also displays cleavage. Kieselgur is very light, with a density of 2.3 g/cm<sup>3</sup> (bulk) and 0.256 g/cm<sup>3</sup> (powder).<br />
<br />
==Availability==<br />
Diatomaceous earth is available in many garden shops as insect killer. It can also be purchased online.<br />
<br />
==Projects==<br />
*Water filtration<br />
*Adsorbing agent<br />
*Thermal insulator<br />
*Make [[dynamite]]<br />
*Catalyst support<br />
<br />
==Handling==<br />
===Safety===<br />
Powdered diatomaceous earth is irritant to lungs and long-term exposure may cause silicosis.<br />
<br />
===Storage===<br />
Diatomite should be stored in closed bottles.<br />
<br />
===Disposal===<br />
No special disposal is required, though it's best to avoid scattering it in air.<br />
