Diatomaceous Earth (DE) is a naturally occurring sedimentary rock, composed of the fossilized remains of tiny hard-shelled aquatic organisms called diatoms. These microscopic wonders have intricate, porous skeletons made of silica, which, over millions of years, accumulate in deposits on ocean floors and in ancient lakes. Silica is common in nature, making up 26% of the earth’s crust by weight, and can come in many forms including sand, emerald, quartz, feldspar, mica, clay, asbestos, and glass. Silicon, a component of silica, does not exist naturally in its pure form as it usually reacts with oxygen and water to form silicon dioxide. Silicon dioxide has two naturally occurring forms: crystalline and amorphous. Most diatomaceous earth is made of amorphous silicon dioxide (Bunch, Bond and Buhl).
DE’s remarkable properties make it a versatile substance with a wide range of applications:
