Fused silica powder

With refined quartz powder as the raw material, special process modification is applied to make fused Silica Powder on the basis that it retains its original characteristics. Organic solvents in polymer, affinity, and other organic solvents greatly increase the filling rate of fused Silica powder.

Fumed quartz

Glass made with fused silica (or silica in amorphous form) is called glass. This glass is not like conventional glass. It does not have any additional ingredients. The glass melts at a lower temperature when it has been added with other ingredients. Therefore,



Has a higher melting point and working temperature. Although fused-quartz and fused are often used interchangeably, fused is superior in optical and thermal properties to fused glass and other types because of its purity.

This is why it’s used in


It is used in the manufacture and maintenance of laboratory equipment. It is able to penetrate ultraviolet light better than any other glasses. This makes it a good choice for making lenses and optical devices that are in the ultraviolet spectrum. Because of its low thermal expansion, fused quartz is an excellent material for making.

Substrata of fused Silica

For precision mirror substrates

Fused quartz has a much lower cost than zircon. Also, its density is significantly less than that of zircon. This means shell manufacturing can be done with Fused. After being carefully chosen, fused quartz can be melted in an arc furnace. The quartzite then is removed. This ensures that the quality is good and there is less impurities. This has ensured that paint slurry stability is not a problem. Research has shown that the durability of fused quartz and silicon sol coatings is usually more than one year. Casting surfaces are easy to clean because of crystallization and phase transition at low temperature.

Performance of Fused Silica Powder Fused Quartz powder

A fusion of silica is made from natural quartz. The raw material is heat-smelted, cools amorphous silicon dioxide, and then processed in a special way. This product is high in purity, has a low thermal expansion coefficient and high internal stress. It also resists high humidity, radioactivity, and other great characteristics. Fused Silica Powder properties: very low linear expansion coefficient; excellent electromagnetic radiation; and chemically stable characteristics, such as chemical resistance to chemical corrosion.

Fused Silica powder Fused Quartz Powder Fused SiO2 Pulver


Here are some steps to prepare fused quartz dust:

1) Crushing;

2) fine grinding;

(3) Pickling the impurity to be removed

4) Ultrasonic cleaning

5) high-temperature fusion;

6) Grinding, rapid cooling

This preparation involves manual screening and pickling for impurities.

Fused quartz is used in integrated circuits of large or very large dimensions, including those with epoxy castables and potting materials. You can also use it in electronics packaging, investment casting and the high-end insulation, coatings, silicone rubber, and other industries. These are just a few of the many applications that fused quartz powder has:


Grate of fused silica


: plate glass, float glass, glass products (glass jar, glass bottle, glass tube, etc. ), optical, transparent, and glass fiber.

2. Ceramic and Refractory Materials: Porcelain embryo material and glaze; kiln with silicon brick, silicon carbide, or ordinary silicon brick.

3. Construction materials: cementitious and road materials; concrete. Artificial marble. Cement physical performance tests materials.

4. Chemical industry: silicates and silicon compounds.

5. Machinery refers to the raw materials used in casting sand or grinding (sandblasting and hard grinding paper), sandpaper, emerycloth, etc. ).

6. Electronics: Silicon metal of high purity, optic fiber for communication etc.

7. Rubber and plastic are used for packing. This can improve wear resistance.

8. Coating: Packaging (can increase the weatherability and durability of coating).

9. Metallurgy: ferrosilicon, silicon alloy, and silicon aluminum all, as well as other raw materials and additives.

10. Aircraft, aerospace: The internal molecular structure of the crystal, its crystal shape, and lattice changing law. It has high temperature resistance, low thermal expansion coefficient, excellent insulation, corrosion resistance and piezoelectric effect.

Fused Silica powder and Fused quartz Powder Storage:

Keep the fused silica in an environment that is dry, cool, and closed. This will prevent moisture from affecting its dispersion and usage effect.

Transport and packing of fused silica powder Fused quartz powder

You can pack it in two plastic bags with the inside.

Packaging of fused quartz powder: vacuum packaging, 1kg/bag and 25kg/bag.
