Diatomaceous Earth (DE) is a naturally occurring siliceous sedimentary mineral, formed by the fossilization of diatoms—single-celled aquatic algae with silica-based skeletons—over millions of years. Endowed with unique physical and chemical properties, it is widely recognized as a high-performance, environmentally friendly multi-functional material, serving various industrial and commercial fields with its outstanding characteristics.
Core Product Characteristics
- 1.Unique Porous Structure & Strong Adsorption Capacity
The most distinctive feature of diatomaceous earth is its intricate porous structure, which is formed by the accumulation of diatom fossils. Under electron microscopy, each DE particle contains countless tiny, uniform pores, with a porosity of over 90% and a specific surface area of up to 65㎡/g—500 to 600 times that of activated carbon. This special molecular sieve-like structure enables DE to exert strong physical adsorption capacity, effectively absorbing harmful gases, moisture, impurities, and heavy metal ions without chemical reactions or secondary pollution.
- 2.100% Natural & Environmentally Friendly
Composed mainly of silica (80-90%), supplemented by small amounts of alumina, iron oxide, and trace minerals (calcium, magnesium, etc.), diatomaceous earth is completely natural and non-toxic. It contains no heavy metals, harmful chemicals, or VOC emissions, fully complying with environmental protection standards of major countries and regions worldwide. Odorless and safe for humans, animals, and the environment, it is ideal for scenarios with high safety and environmental requirements, such as food processing, indoor decoration, and water purification.
- 3.Excellent Chemical Stability & Durability
Diatomaceous earth boasts remarkable chemical stability, with strong resistance to acid, alkali, high temperature, and corrosion. It can maintain stable performance even in harsh environments (high temperature, high humidity, strong acid-alkali conditions), without aging, decomposition, or releasing harmful substances. Compared with synthetic materials, it has a longer service life, ensuring reliable and long-term application effects in various scenarios.
- 4.Versatile Functionality & High Cost-Effectiveness
With its superior performance, diatomaceous earth has diverse applications and high cost-effectiveness. Its strong filtration and adsorption capacity make it an ideal filter aid in food, beverage, pharmaceutical, and water treatment industries, effectively filtering tiny particles (0.1-1.0um) to improve product clarity and quality. In construction, it is used to produce thermal insulation, sound insulation, and moisture-proof materials due to its low thermal conductivity. In agriculture, it serves as an environmentally friendly physical insecticide and soil amendment, enhancing soil aeration and water retention.
- 5.High Purity & Stable Quality
Through advanced processing technology, our diatomaceous earth products have high purity (silica content up to 90%), uniform particle size distribution, and stable performance. The strict quality control system ensures consistent batch quality, avoiding performance fluctuations, and meeting the personalized needs of different industries and application scenarios.
As a natural, environmentally friendly, and multi-functional mineral product, diatomaceous earth perfectly aligns with the global trend of green and sustainable development, providing high-quality, safe, and efficient solutions for various fields.
