Diatomaceous earth (MF: O2Si, MW:60.0843) primarily consists of amorphous silica (SiO₂・nH₂O). It exhibits exceptional acid resistance, being insoluble in strong acids such as hydrochloric, sulphuric, and nitric acids. It demonstrates good alkali resistance, reacting slowly with strong alkalis at ambient temperatures, though this reaction accelerates at elevated temperatures. Additionally, it possesses porous adsorption properties, filtration capabilities, and thermal insulation qualities.

Utilising its porous structure in filtration applications:
– Clarification filtration for food and beverages including beer, wine, fruit juices, and soy sauce;
– Filtration of antibiotic and vitamin solutions;
– Filtration of drinking water and industrial effluents (e.g., electroplating wastewater, petroleum wastewater).
Applications in adsorption:
– Indoor air purification; wastewater treatment (adsorption of oil contaminants, dyes, heavy metal ions);
– Daily necessities such as desiccants and deodorisers;
– Agricultural applications including soil conditioners and pesticide carriers.
Leveraging its low density, high dispersibility, and chemical stability for use as fillers and additives in plastics/rubber, coatings/inks, paper fillers, etc.
Leveraging its thermal insulation, heat resistance, and breathability for building materials:
– Insulation materials for building exteriors and industrial furnace insulation;
– Functional building materials like diatomaceous earth interior panels and diatomaceous mud;
– Fireproof boards and coatings incorporating diatomaceous earth.
Other specialised applications, including feed additives, auxiliaries in steelmaking and casting, and sample carriers for electron microscopes.
