Kieselguhr, also known as diatomaceous earth, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It is formed from the fossilized remains of diatoms, single-celled algae with silica shells. This porous material possesses a high absorptive capacity and is chemically inert, making it useful in various industrial and commercial applications. Its unique structure allows it to filter liquids, absorb liquids, and act as a mild abrasive. It is utilized across many fields, from filtration and insulation to absorbents, filler material, and even as an insecticide. The origin of the term is German and literally translates to 'pebble earth'.
