What is Silicon Dioxide? Si02 is the chemical name of silicon dioxide: silicon dioxide is an acidic oxide and a solid at normal temperatures. Silicon dioxide is insoluble in water and acid but soluble in hydrofluoric acid and hot concentrated phosphoric acid and can act with molten alkalis. Silicon dioxide is widely used, mainly for making glass, water glass, pottery, enamel, etc. Pure natural silicon dioxide crystal is a hard, brittle, insoluble, colorless, and transparent solid, and It is often used to manufacture optical instruments, etc. Silicon Dioxide is widely found in nature and forms rocks with other minerals. Natural Silicon Dioxide is called Silicon Dioxide, which accounts for about 12% of the mass of the earth's crust. It exists in crystalline and amorphous forms. Quartz crystal is crystalline silicon dioxide with different crystal forms and colors. The colorless and transparent crystal in quartz is usually called crystal. The crystal with a colored ring, band, or layer is called agate (containing impurities).
Material structure of Silicon Dioxide The properties of silicon and carbon are similar, but the properties of their oxides are very different. SiO2 is a molecular crystal, while SiO2 is an atomic crystal. SiO2 is a three-dimensional network structure formed based on the silicon-oxygen tetrahedron. In the crystal structure, four valence electrons of silicon atoms form four covalent bonds with four oxygen atoms, Si atoms are at the center of the tetrahedron, and O atoms are at the apex of the tetrahedron. Each silicon atom is connected to four oxygen atoms; each oxygen atom is connected to two silicon atoms. The smallest ring in the crystal is composed of 12 atoms (6 silicon atoms and six oxygen atoms). Six rings share each silicon. The number ratio of silicon and oxygen atoms in the crystal is 1:2.
Health hazards of Silicon Dioxide Silicon dioxide has important uses in daily life, production, and scientific research, but sometimes it can cause harm to the human body. Silicon dioxide dust is extremely fine, with a specific surface area of more than 100m2/g, which can be suspended in the air. If people inhale the dust containing silicon dioxide for a long time, they will suffer from silicosis. Because silicon was formerly known as silicon, silicosis was known as silicosis. Silicosis is an occupational disease and its occurrence and severity. It depends on the content of dust in the air and Silicon Dioxide in the dust, as well as the contact time with people. People who work in places with high content of Silicon Dioxide dust for a long time, such as mining, sanding, sandblasting, ceramics, refractory materials, and other places are vulnerable to this disease. Therefore, in these dusty workplaces, strict labor protection measures should be taken, and various technologies and equipment should be used to control the dust content in the workplace to ensure workers' health.
Price of Silicon Dioxide Silicon Dioxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Silicon Dioxide. A large amount of large amount will be lower. The price of Silicon Dioxide can be found on our company's official website.
