What is Silicon Dioxide? Silicon dioxide are located at the center of the regular tetrahedron, and four oxygen atoms are located at the top corners of the regular tetrahedron. Oxygen atoms connect many such tetrahedrons at the top corners. Two tetrahedrons share each oxygen atom; each oxygen atom is combined with two silicon protons. The simplest formula of silicon dioxide is SiO2. However, SiO2 does not represent a simple molecule. Pure natural silicon dioxide crystal is a hard, brittle, insoluble, colorless.
Chemical properties of Silicon Dioxide 1. Relatively stable chemical properties. It is insoluble in water and does not react with water. It is an acid oxide and does not react with ordinary acid. Gaseous hydrogen fluoride reacts with silicon dioxide to generate gaseous silicon tetrafluoride. It reacts with a hot strong alkali solution or molten alkali to generate Silicon dioxide and water. It reacts with various metal oxides to generate Silicon Dioxide at high temperatures. It is used for manufacturing instant glass, optical instruments, chemical vessels, ordinary glass, refractory materials, optical fibers, ceramics, etc 2. The nature of silicon dioxide is inert. Except for hot concentrated phosphoric acid, it does not react with halogen, hydrogen halide, sulfuric acid, nitric acid, or perchloric acid, except fluorine and hydrogen fluoride. The common concentrated phosphoric acid (or pyrophosphoric acid) can corrode silicon dioxide at high temperatures and produce heteropoly acids. The molten borate or boron anhydride can corrode silicon dioxide at high temperatures. Given this characteristic, borate can be used as a flux in ceramic firing 3. In addition, hydrogen fluoride can also be an acid that can dissolve Silicon Dioxide to form water-soluble fluorosilicic acid: SiO4HF=SiF42HO To sum up, Silicon Dioxide makes glass, timely glass, sodium Silicon dioxide, optical fiber, important parts of the electronic industry, optical instruments, handicrafts, and refractories, which are important materials for scientific research. Silicon Dioxide, also known as Silicon Dioxide, has a chemical formula of SiO. There are crystalline Silicon Dioxide and amorphous Silicon Dioxide in nature.
Mineral classification of Silicon Dioxide Silicon Dioxide minerals in sedimentary rocks mainly occur in clastic and siliceous rocks. They can be both terrigenous minerals and authigenic minerals. The genesis of these two Silicon Dioxide minerals is very different, and they must be distinguished. Terrigenous minerals are clastic quartz particles. Some clastic quartz particles contain inclusions, and The inclusion can be divided into gas-liquid inclusion and mineral inclusion. The mineral inclusion can also be divided into granular, acicular, and flaky, according to the minerals' crystal shape. The type of inclusion is related to the source of quartz. Generally speaking, most of the gas-liquid inclusions (milky quartz) almost all come from quartz veins; Quartz in schist and other high-grade metamorphic rocks has rare gas-liquid inclusions; Quartz in volcanic rocks is often as clear as water and rarely contains inclusions; Most of those with rutile acicular inclusions come from granite. However, because the occurrence of the inclusions in the parent rock is complex, the particles are very small, and the identification is difficult, its application is quite limited.
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.
