High Purity Silicon Dioxide SiO2 powder CAS 7631-86-9, 99.9%

Silicon dioxide is also called silica. It's an oxide of silicon and has the chemical composition SiO2. Silica, which includes silica found in quartz and quartz sand, is collectively called silica. Particle Sizes: 10-30nm
Purity: 99.5-99.9%

Silicon Dioxide SiO2 powder
Silica Oder silicon dioxide It is The chemical formula for silicon oxide is SiO2. It is found as the most widespread form in nature. quartz diverse organisms. Silica, which is the principal component of sand, can be found in many places around the globe. Silica is an extremely complex, abundant and diverse material family. It can come in the form mixed minerals or synthetic products. Notable examples include Fused silica , fumed silica , silica gel aerogel . It can be used to make structural materials and microelectronics, which are electrical insulators.

Breathing in finely divided herbs A crystal silica This toxic substance can inflame the lung and cause severe inflammation, such as silicosis or bronchitis. It also causes systemic autoimmune disorders like lupus, rheumatoid, and lupus. Amorphous silica may cause temporary inflammation in the lungs. However, all symptoms can be treated.

Amorphous silica is formed by long-range arrangements of oxygen and silicon atoms. A silicon dioxide crystal has four oxygen atoms at its four corners. The silicon atoms will be at the centre of a regular trihedron. Numerous tetrahedrons can be held together with oxygen atoms located at their four corners. The two tetrahedrons that share an oxygen atom are called a tetrahedron. This means each oxygen-atom is bound to two silicon molecules.

Silica's molecular formula is its simplest. SiO2 SiO2 doesn't represent a simple molecular (it is the ratio of number of silicon and oxygen in silica crystals). A pure crystal of natural silica is fragile, hardy, insoluble and transparent. It's often used for the manufacturing optical instruments.

Colloidal silicon dioxide Gaseous silica is produced by hydrolysis from silica compound, and is used for many medicines and foods.

Silicon Dioxide SiO2 powder performance

1 It has a high surface residue button of unsaturated hydroxyl groups and a different bonding status of hydroxyl groups. This makes it very scatter-friendly.

2 Silicon oxides can be synthesized using sol-gel. This allows for the synthesis of tiny, uniformly sized particles.

3 To ultraviolet light, and displays high reflection characteristics (200 70% reflectivity, 280nm), 80%. For visible wavelengths (400–800nm), reflectivity 85%. The band of 800-1350 near-infrared reflectance is also higher than 70%.

Chemical Composition


































It is simple. Silicon Dioxide siO2 powder produced?
Amorphous silicon dioxide preparation method
Preparing amorphous silica involves five steps: preparation of silica gel; sintering and cleaning; drying;
1. Silica gel preparation
Silica gel is made from silicon tetrachloride. Pulverizing organic silicon compounds, such as tetramethoxy siloxane, can also produce it. Fumed silica, however, can make silica gel.
2. Granulation Process
A silica powder can be made by dry drying silicone gel and then grinding the powder.
3. Insintering
Silica powder from the granulation is sintered at temperatures between 800 and 1450 degrees Celsius. Thermal plasma can be spheroidized to release argon at a preset flow rate. The output is then converted at a specified frequency in order to create plasma. Plasma torch: The sintered silica is heated to 2000°C, which will melt it.
4. Cleaning
After the spheroidization, any fine powder remaining on the surface of the silica powder spheroidized is removed.
5. Drying
Following the cleaning, silica powder will be dried.

Silicon Dioxide Uses:
Silica is used in the manufacture of many products. silicon dioxide glass Glass, quartz, water, and optical fibre are all important elements of the electronics industry. These include optical instruments, handicrafts, refractory material, and materials that can be used for scientific research.

1. Most glass is made from silica. If silica is melted with other minerals, the freezing points reduction principle decreases the melting temperature and improves fluidity. SiO2's glass transition temperature is approximately 1475K. The glass transition temperature of fused SiO2 is about 1475K. Most ceramic glazes consist largely of silica.
2. Silica is also a good additive.
3. Silica is especially suitable for the granulation and extraction of oils and other extracts.
4. Silicium dioxide, as a disintegrant can significantly improve the fluidity and bulk density of the granules. It also increases the hardness of the tablets. You can use it as an internal desiccant to increase the stability of your drug.
5. Silica is also used to thicken liquid preparations, as a defoamer and filter aid.
6. 95% to 90% of commercial silica uses (sand) are in the construction sector, like the production concrete (Portland concrete).
7. Due to its light diffusion and natural absorption, silica has a significant role in cosmetics.
8. For the semiconductor industry, passivating silicon's surface through thermal oxidation is essential. It's used to make metal oxide field-effect transistors with MOSFET (metal oxide semiconductor field effects transistors) or silicon integrated circuit chips using planar technology.
9. You can use silica to extract DNA or RNA, as it is able to bind nucleic acids when there are chaotropic agents.
10. Because silicon dioxide can be used as a natural semiconductor oxide instead of other semiconductors, such as indium-phosphide and gallium arsenide, it is much more popular.
11. It is possible to grow silicon dioxide on top of the surfaces of silicon semiconductors. Silicon oxide can be applied to the silicon substrate as a protective layer during diffusion.
12. Silicon dioxide in food Silica is used in food manufacturing as an anti-caking ingredient in creams or spices. This allows for fine powder flow and absorbs moisture.
13. Silicon dioxide in supplements .
