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 dust: Silica or silica are both forms of the silicon oxide SiO2. quartz, which is also used in various organisms, is the most commonly found form. Silica, the principal component of sand, is found in many areas of the world. Silica is one of most abundant and complex material families. This can come in the form mixed minerals and synthetic products. fused Silica Fumed Silica Silica gel and Aerogel are just a few examples. It can be used to make structural materials and microelectronics, which are electrical insulators. The inhalation finely divided or crystalline silica is toxic. It can lead to severe inflammation of the lung tissues, silicosis (lung cancer), and other systemic autoimmune disorders like lupus, rheumatoid, and lupus. Amorphous silica inhaled at high levels can cause temporary inflammation that can not be reversed. 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. SiO2 describes the most basic molecular formula of silica. But SiO2 is not a simple molecule. Instead, it represents just the ratio of number of silicon and oxygen atoms present in silica crystals. A pure crystal of natural silica is insoluble, hard, translucent, non-colorless, and colorless solid. It’s often used for the manufacturing optical instruments.

How Silicon Dioxide, SiO2 Powder is produced? Amorphous silicon dioxide preparation method Preparing amorphous silica involves five steps: preparation of silica gel; sintering and cleaning; 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 is obtained by granulation and sintered at 800°C to 1450°C. At a predetermined rate the obtained sintered silica is mixed with water and heats to a boiling point. 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 as a raw material to manufacture Silicon dioxide Glass. Quartz glass, water glasses, optical fibers, key parts of electronics, handicrafts, refractory and optical materials. It also serves as a material important 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 primarily 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 drug’s stability. 5. Silica is also used to thicken liquid preparations, as a defoamer and filter aid. 6. 95% of all silica’s commercial uses are within the construction industry. For example, the creation of Portland cement 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 is in food – Food producers use silicon dioxide as an anticaking agent in their creams or spices to prevent the formation of lumps or retain moisture. 13. Silicon dioxide in supplements. Storage condition of Silicon Dioxide SiO2 pulver : You should keep nanosilicon dioxide SiO2 powder in a dry and clean environment. Shipping and Packing of Silicon Dioxide SiO2 powder – You can pack it in two plastic bags with the inside. Silicon Dioxide SiO2 Powder Packaging: 100g, 500g and 1kg/bag. 25kg/barrel.
