What is the application scope or characteristics of metal silicon powder?
Metal silicon powder, to put it simply, is the powder state of metal silicon. ZhenAn metal silicon powder manufacturer introduced that since the main component of metal silicon powder is silicon, it is undoubtedly similar to the properties and uses of silicon. Next, let's take a brief look at the application scope or characteristics of metal silicon powder!
Silicon has two polar covalent bonds: amorphous silicon and crystalline silicon. Amorphous silicon is a black powder, which is actually a microcrystal. Crystalline silicon has the molecular structure and semiconductor properties of diamond, with a melting point of 1410℃, a melting point of 2355℃, a relative density of 2.32~2.34 g/cm3, a hardness of 7, and brittleness.
Chemical silicon refers to metallic silicon used in the production of silicone materials and polysilicon. From a global perspective, the consumption of silicon used in the metallurgical industry exceeds that of chemical silicon. However, with the rapid development of science and technology, the use of chemical silicon in industries such as silicone materials and semiconductor production has continued to expand, and is widely used in the production of silicone monomers and polymer methyl silicone oils, silicone, silicone resin building anti-corrosion, waterproof coatings, etc. They have unique properties such as heat resistance, insulation, radiation resistance, and moisture resistance. Used in electrical equipment, aviation, machinery, chemical plants, pharmaceuticals, national defense, and construction units. As the core electronic components of integrated circuit chips, more than 95% are made of semiconductor silicon, which is the backbone of modern information manufacturing.
Amorphous silicon has bright physical properties and can burn violently in O2. It reacts with non-metallic materials such as halogen lamps, nitrogen, and carbon at high temperatures, and can also react with metals such as magnesium, calcium, and iron to form silicides. Amorphous silicon is basically insoluble in strong oxidants and organic matter including hydrochloric acid, but it can be dissolved in a mixture of sodium cyanide and hydrochloric acid. Concentrated sodium hydroxide solution can dissolve amorphous silicon and release radon gas. Crystalline silicon is relatively inactive and does not combine with O2 even at high temperatures. It is also insoluble in any strong oxidant and organic matter, but it can be dissolved in a mixture of sodium cyanide and hydrochloric acid and concentrated sodium hydroxide solution.
