diatomite

Diatomaceous earth is a kind of sediment formed by floating diatom fossils in the ocean, and the main component of silicon dioxide (SiO2). Diatomaceous earth is white or light yellow, with high porosity and specific surface area, so it has good adsorption and filterability, as well as high grinding and insulation properties. Diatomaceous earth can be used in a variety of fields such as filtration, purification, corrosion protection, grinding and polishing, and insulation.

Among them, diatomaceous earth can be used for polishing treatment of metal and non-metal workpiece surfaces. There are also widely used for liquid and gas filtration in drinking water, sewage, food, beverage and pharmaceutical industries. Diatomaceous earth can also be used in the preparation of health food, cosmetics, oral cleansers and other products, and is widely used in construction materials, environmental protection materials, etc.

Product nature


  1. Physical properties: Diatomite has high porosity and specific surface area, the  white or light yellow powder, which has good adsorption, filterability and grinding property, but also has good insulation.

  2. Chemical properties: The main component of diatomaceous earth is silicon dioxide (SiO2), which has high chemical stability and is insoluble in water and most organic solvents, but can react with hydrofluoric acid.

  3. Biological properties: Diatomaceous earth is non-toxic and harmless to organisms, and can be decomposed and recycled by nature.

  4. Thermal properties: Diatomite has good heat resistance, can withstand higher temperatures, and has a certain degree of heat insulation.

  5. Medical properties: Diatomaceous earth can absorb harmful substances such as organic compounds and heavy metal ions, so it is widely used in pharmaceutical, health care products and other products in the medical field.


Scope of application

Diatomaceous earth has a wide range of applications, mainly including the following aspects:

  1. Grinding and polishing: The high hardness and dispersion of diatomite make it the preferred material for abrasives and polishes, and it is widely used in precision grinding and polishing in semiconductor, optical, ceramics, metals and other industries.

  2. Filtration and purification: The high porosity and specific surface area of diatomite make it an excellent filtration material, which is widely used in water treatment, solid waste treatment, food, beverage, consumer electronics and other fields.

  3. Construction and environmental protection: Diatomaceous earth can adsorb organic compounds and harmful substances such as formaldehyde, so it is widely used in construction materials, environmental protection materials and other fields, and can play a better role in purification and deodorization.

  4. Cosmetics and health care products: The adsorption capacity of diatomaceous earth makes it an important raw material for cosmetics and health care products, and is widely used in sunscreen, facial mask, oral cleanser and other fields.

  5. Medicine and life sciences: Diatomaceous earth can adsorb harmful substances and microorganisms, and is widely used in various pharmaceutical and pharmaceutical products for medical purposes. At the same time, diatomaceous earth can also be used in cell culture, gene sequencing and other life science research fields.
