diatomitowa

Diatomitowa, in Polish, is the feminine form of the adjective relating to diatomite, a natural siliceous sedimentary rock composed mainly of the fossilized remains of diatoms, a group of microscopic algae. In English, this material is called diatomite or diatomaceous earth. It is typically light-colored, very porous, and soft, and it occurs in deposits formed by the accumulation of diatom frustules in aquatic environments.

Composition and properties: Diatomite is predominantly silica (SiO2) organized into tiny, hollow shells (frustules) of diatoms. The material has very high porosity and surface area, low density, and a flaky to powdery texture. It is relatively soft, with a Mohs hardness around 3 to 4, making it easy to grind or crumble. Its purity and impurities vary by deposit, influencing color and suitability for food-grade use.

Uses: It is widely used as a filtration medium for liquids such as drinking water, beer, wine, and fruit juices. Food-grade diatomite serves as a clarifying agent and sometimes as a supplement; non-food-grade forms are used as abrasive polishing agents, fillers in paints, plastics, and rubber, and as carriers for pesticides and enzymes. It is also used in agriculture as a soil conditioner and in pest control (diatomaceous earth), where the sharp microscopic particles damage insect exoskeletons and desiccate them.

Safety and environment: Inhalation of diatomite dust can irritate the respiratory tract and prolonged exposure to crystalline silica poses health risks. Proper handling, dust control, and protective equipment are recommended. Diatomite deposits are mined resources; extraction can affect local ecosystems, so responsible mining practices and compliance with regulations are important.
