Product Description: High-Purity Diatomite for Horticulture, Filtration & Industry

Diatomite, also known as diatomaceous earth (DE), is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It is composed of the fossilized remains of diatoms—microscopic hard-shelled algae. Our high-purity diatomite (Cas No. 61790-53-2), responsibly sourced from China, offers exceptional porosity, low bulk density, and a high surface area. These unique physical and chemical properties, including its high silica content and chemical inertness, make it an indispensable raw material across multiple sectors, including horticulture, water filtration, food and beverage processing, industrial absorbents, and cosmetics.

The controlled particle size distribution and consistent quality of our diatomite ensure reliable performance in every application. Whether used as a premium soil amendment to enhance plant growth, a high-efficiency filter aid to achieve crystal-clear liquids, or a natural abrasive for polishing, our product delivers superior results while promoting environmental sustainability.

Key Benefits as a Horticultural Substrate

In horticulture, yellow diatomite particles are particularly valued for their ability to dramatically improve soil structure. Its highly porous structure acts like a sponge, absorbing and retaining moisture while simultaneously ensuring excellent drainage. This critical balance is essential for preventing root rot and other water-related issues in plants, while promoting robust, healthy root development.

Furthermore, diatomite's inert chemical nature ensures it does not alter the soil pH or nutrient composition, providing a stable and healthy environment for a wide range of plant species—from succulents and cacti to high-value greenhouse crops and hydroponic systems. It is widely used as a soil amendment, potting mix component, seed starter, and lawn conditioner. Its lightweight structure reduces soil compaction, improving oxygenation around the root zone and boosting overall plant vigor and yield.

• Enhances soil aeration and drainage
• Increases water holding capacity
• Provides a stable, inert growing environment
• Suitable for organic farming and soilless culture

Superior Filtration and Industrial Applications

As a filter material, diatomite's high porosity and large surface area enable it to effectively trap suspended solids, impurities, and contaminants down to sub-micron levels. It is widely employed as a filter aid in water treatment plants, swimming pools, aquariums, and industrial processes such as the production of beer, wine, juices, and pharmaceutical liquids. Its natural abundance and non-toxic nature make it a sustainable and eco-friendly alternative to synthetic filtration media.

Our food-grade diatomite meets rigorous safety standards, ensuring purity and reliability for sensitive applications. Beyond filtration, this versatile mineral is also used as a mild abrasive in polishes and toothpastes, an absorbent for hazardous spill cleanup, an insulator in refractory materials, and a lightweight aggregate in construction products.

• Effective filtration down to micron and sub-micron levels
• Ideal for water purification, food & beverage processing, and chemical filtration
• Natural, non-toxic, and environmentally sustainable
• Available in both industrial and food-grade quality
