Diatomaceous Earth: Natural Porous Mineral Material Empowering Green Development Across Industries

Diatomaceous earth (DE) is a biogenic siliceous sedimentary rock. It is formed by the geological deposition of ancient aquatic single-celled diatom remains over millions of years. Its main component is silicon dioxide, accompanied by small amounts of aluminum oxide, iron oxide, calcium and magnesium oxides and other components. After crushing, purification, calcination, air classification and fine screening, raw ore is processed into diatomaceous earth powder of various particle sizes. It is a widely used environmentally friendly non-metallic mineral raw material.

The most prominent feature of diatomaceous earth is the unique honeycomb microporous structure retained inside the diatom shells. It has abundant pores and large specific surface area, delivering excellent adsorption capacity and permeability. Meanwhile, it is lightweight, chemically inert, high-temperature resistant and heat-insulating. Its physical and chemical properties are stable, and it rarely reacts with acidic or alkaline substances. These core characteristics lay a solid foundation for its applications in multiple industrial sectors.

Main Application Fields

1. Filtration IndustryAs a classic filter aid, it traps fine impurities through physical screening and adsorption. Food-grade calcined diatomaceous earth is used for clarifying and filtering beer, wine, fruit juice, edible oil, syrup and other beverages and oils. Industrial-grade products are applied in drinking water purification, industrial wastewater treatment and swimming pool water treatment, effectively removing suspended solids, partial organic matter and trace impurities to keep filtrate clear and stable.
2. Building Materials & CoatingsIt serves as the core raw material of diatom mud. Relying on its porous structure, it can adjust humidity and absorb peculiar smells, with sound insulation performance. It is also used as raw material for thermal insulation and fireproof boards, reducing the thermal conductivity of building materials with lightweight and heat-insulating features. It acts as a functional filler in coatings, rubber and plastic systems to improve the wear resistance and anti-aging performance of coatings and optimize product structure.
3. Environmental Protection & AgricultureWith strong adsorption capacity, it can adsorb water pollutants, heavy metals and organic contaminants for soil remediation, improving soil air permeability and water retention capacity. It can also be used as feed carrier and auxiliary material for soil improvement in planting and breeding industries.
4. Chemical & Other IndustriesIt can be used as catalyst carrier in fine chemical and biosynthetic reaction systems. It is also applied in abrasive materials, daily chemical fillers, thermal insulation refractory materials and other scenarios to meet diversified industrial production requirements.
