Diatomite is a kind of siliceous rock of biological causes, mainly consists of remains of ancient diatoms. Diatomite is widely used as insulation, soundproof material due to it is the poor conductor of heat, sound and electricity.
General physical properties of diatomite:
1: light yellow or light grey, white
2: soft, low density
3: porous
4: strong water absorption
The main chemical component of diatomite is SiO2, with small amount of Al2O3, Fe2O3, CaO and MgO, etc.
| SiO2 | 80%-90% |
| Fe2O3 | 1%-1.5% |
| Al2O3 | 3%-6% |
| Color | Light Yellow |
| White | |
| Size(mesh) | 100 |
| 200 | |
| 325 |
Diatomite is widely used as insulation, soundproof material due to it is the poor conductor of heat, sound and electricity.
Physical Properties:

| Permeability(Darcy) | 1.5-3.5 |
| Median particle size(microns) | 24 |
| PH (10% slurry) | 10 |
| Moisture (%) | 0.5 |
| Specific gravity | 2.3 |
| Acid solubility % | <3 |
| Water solubility % | <0.5 |
Advantages of Diatomite:
Diatomaceous earth does not contain harmful chemical substances. In addition to non-combustible, sound insulation, waterproof, light weight and heat insulation, it also has the functions of dehumidification, deodorization, and purification of indoor air. It is an excellent environmentally friendly indoor and outdoor decoration material.
Application:
Paints Industry:
The diatomite paint additive product has the characteristics of large porosity, strong absorption, stable chemical properties, wear resistance, heat resistance, etc., which can provide coatings with excellent surface properties, compatibilization, thickening and improving adhesion.Due to its large pore volume, it can shorten the drying time of the coating film. It can also reduce the amount of resin and reduce costs. It has been used as a designated product by many large international paint manufacturers and is widely used in water-based ditom mud.
Fiter Aids:
Nowadays diatomite is commonly used in vegetable oil, edible oil, food, beverage, beer manufacturing process for fitration use.
Pesticide Industry:
Wettable powders, dryland herbicides, paddy field herbicides and various biological pesticides all have diatomaceous earth.
Compound Fertilizer Industry:
Compound fertilizer for various crops such as vegetables, flowers and trees. Diatomite has a good performance in crop growth and soil improvement.
Building Insulation Industry:
Diatomaceous earth has a good performance in wall insulation, heat insulation, sound insulation decorative panels, floor tiles, ceramic products; etc.
Rubber Industry:
Diatomite is used in various rubber products such as vehicle tires, rubber tubes, triangle belts, conveyor belts and car mats; etc.
Feed Industry:
Could be used as additives to various feed such as for pigs, chickens,ducks, geese, fish, birds and aquatic products ; etc
Polishing&Friction Industry:
Diatomite could be used in polishing brake pad of vehicles and the manufacturing of mechanical steel boards, wood furniture and glass; etc.
Leather&Artificial Leather Industry:
Diatomite is used in all kinds of leather such as artificial leather products.
Paper Industry:
Diatomite is commonly used in paper manufacturing such as office paper and industrial papers.
