Celite® 545, filter aid

Celite or diatomite are naturally occurring sedimentary rocks containing silica which can be crumbled into an off-white powder. The substance consists of fine particles ranging from 10 to 200μm. Celite is used as a medium of filtration because of its high porosity. Commonly called as dietomaceous earth, this soft powder-like substance is used in applications including filtration, heat insulation and adsorption.
