DESCRIPTION: Diatomaceous Earth

Also known as D.E., diatomite, or kieselgur/kieselguhr - is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 μm to more than 1 mm, but typically 10 to 200 μm.

The typical chemical composition of oven-dried diatomaceous earth is 80–90% silica, with 2–4% alumina and 0.5–2% iron oxide.
