Uses of Diatomite as an Absorbent
Plant food manufacturers use diatomite to assist with the slow release of water and nutrients to plants. Similarly, pesticide and herbicide manufacturers use diatomite as an absorbent of the toxic chemicals that will slowly be released to destroy toxic insects and plants.
Diatomite is capable of absorbing oil, grease and hazardous wastes without changing its own chemical properties and causing additional hazards. Diatomite is frequently employed for hazardous waste cleanup in chemical plants and industrial sites.
Most cat litter contains diatomite, as it acts as both a filter for odors and an absorbent of liquids.
Other Uses
Diatomite is also frequently used as a filter. Its porosity makes it ideal for filtering impurities out of greases, oils, beers, wines, and various impurities and debris out of public water systems.
Diatomite is also used as a filler in soap, detergents, paper, brick, tile and various paints and plastics.
In the past, diatomite's mild abrasive properties have made it a choice ingredient for metal polishes and toothpaste.
