Silicon Dioxide SIO2 powder how is it made? Procedure for making amorphous silica dioxide There are five main steps to making amorphous silica: preparation of silica Gel, sintering process (cleaning), drying process and the cleaning process. 1. Silica gel preparation Silica gel can be obtained by either crushing silicon trichloride or pulverizing organic compounds (such like tetra méthoxy siloxane), as well as using fumed silicon to obtain high-quality gel. 2. Granulation It is possible to obtain silica powder of the desired yield by drying and pulverizing the silicon gel. 3. Process of Sintering Silica powder made from granulation can be sintered at 800°C to 1450°C. With the plasma torch, silica powder from the granulation process is heated at 2000°C to melt. 4. Cleaning After the spheroidization stage, the fine powder adhered to the surface the silica powder spheroidized is removed. 5. Drying The silica paste is then dried. Silicon Dioxide Uses: Silica, a natural material, is important for the production of silicone dioxide glass. It also makes quartz glass, hydro glass, and optical fiber. 1. Glass production is dominated by silica. Silica melts with minerals. The freezing point reduces the melting points and enhances fluidity. SiO2 in pure form has a glass melting point of approximately 1475K. Fusioned SiO2 SiO2 does not melt but solidifies into glass if it is cooled quickly. Ceramic glazes mainly consist of silica. 2. Silica can also serve as an ingredient, an excellent flow promoter, primarily used as a pressing agent, anti-sticking and glidant. 3. Silica is especially well-suited for the granulation oils and extracts. 4. Silica dioxide acts as a disintegrant and can enhance the fluidity of the powders, the bulk density and the hardness in the tablet. Silicon dioxide can be used in the manufacturing of granules as an external desiccant, which will increase drug stability. 5. Silica can also serve as a thickener in liquid preparations and as a filtering aid. 6. 95% or more of the silica’s commercial uses are within the construction industry. For example, the concrete production (Portland cement concret). 7. Silica’s natural light diffusion capabilities and absorption play an important role in cosmetics. 8. This is critical for the industry of semiconductors. It is commonly used to make metal oxide semiconductor field effects transistors, MOSFET (metal oxide semiconductor field-effects transistors), and silicon integrated chip chips (using planar technique). 9. The extraction of DNA andRNA can be done with silica because it can bind directly to nucleic substances in the presence chaotropic compounds. 10. The use of silicon dioxide is greater than that of indium and gallium phosphide because it’s a natural silica oxide. 11. The silicon surface can be coated with silicon dioxide. As a diffusion mask, the silicon oxide layer acts as protection for the silicon surface. 12. Silicon oxide in food Food Manufacturers use Silica as an anticaking agent to protect spices or creams from drying out. It is also used to absorb moisture and ensure powders are finely dissolved. 13. Silicon dioxide in supplements. Storage Situation of Silicon Dioxide siO2 powder: Keep nano silicon dioxide SiO2 dust in an environment that is dry, cool, sealed, and protected from air.
