Diatomaceous Earth
Diatomaceous Earth is composed of the fossilized remains of tiny aquatic organisms called diatoms, whose skeletons are made of silica. Over time, these diatoms accumulate in the sediments of rivers, streams, lakes, and oceans, leading to the formation of silica deposits, which are mined today.
Silicon, a component of silica, does not occur naturally in its pure form but typically reacts with oxygen and water to form silicon dioxide. Silicon dioxide has two natural forms: crystalline and amorphous. Most Diatomaceous Earth consists of amorphous silicon dioxide, though it may contain trace amounts of crystalline silicon dioxide.
