Kieselguhr

Kieselguhr, also known as diatomaceous earth, is a natural, soft sedimentary rock composed mainly of the fossilized remains of tiny diatom algae. These microscopic structures have silica-rich shells that give the material a porous, lightweight texture. It’s often used as a filtering agent due to its ability to trap small particles, as well as in products like abrasives, absorbents, and pest control powders. Kieselguhr is valued for its inertness, high porosity, and eco-friendliness, making it useful in many industrial, agricultural, and health-related applications.
