Diatomaceous Earth (DE) is a naturally occurring, soft, siliceous sedimentary mineral formed from the fossilized remains of microscopic aquatic organisms known as diatoms . These organisms possess silica-based cell walls, which accumulate over millions of years to form deposits rich in amorphous silica (SiO₂) .
DE is characterized by its highly porous microstructure , extremely low density , and large internal surface area . This unique morphology enables outstanding filtration efficiency, adsorption capacity, and thermal insulation performance . Chemically inert and thermally stable, diatomaceous earth functions as a natural filter aid, absorbent, and lightweight filler across a wide range of industries.Unlike synthetic silica, DE offers naturally occurring pore networks , providing efficient permeability and adsorption without complex surface modification.
