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 world. 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 aromas Crystalline 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 arrangement and disordered order of the 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 (just the ratio among the silicon atoms and oxygen atoms of silica crystals). A pure crystal of natural silica is insoluble, hard, transparent and colorless solid that's often used for the manufacturing of 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%.

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 process; drying process.
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 800°C to 1450°C. 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
The fine powder sticking to the surface of the silica powder spheroidized is removed.
5. Drying
Following the above process, silica powder should be dried.

Silicon Dioxide Uses:
Silica is used in the manufacture of many products. silicon dioxide glass Quartz glass, Water glass, Optic Fiber, are all important elements of the electronic industry. These include optical instruments, handicrafts, refractory material, and an important component 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 mainly 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. The construction industry accounts for 95% of all commercial uses of silica, or sand. This includes the production of 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 protect silicon surfaces during diffusion. It can also be used to mask diffusion.
12. Silicon dioxide in food Food producers use silica as an anti-caking ingredient in creams or spices. This allows for fine powder flow and absorbs moisture.
13. Silicon dioxide in supplements .
