The semiconducting properties of silicon metal powder
As we all know, silicon metal powder is made of silicon metal grinding, therefore, we can say that silicon metal is an important raw material for the production of silicon metal powder. Metal silicon is also known as crystalline silicon or industrial silicon, its main use is as an additive in non-iron based alloys. Silicon metal is made of quartz and coke smelted in an electric furnace. The content of silicon element is about 98%, and the other impurities are iron, aluminum, calcium and so on. According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into a variety of different grades. In addition, there are many additional products of silicon metal, such as silicon powder, silicon edge, black silicon, silicon slag, etc. Silicon powder, also known as silicon powder, silicon powder or silica fume, it is widely used in refractory materials and concrete industry. At room temperature insoluble in acid, soluble in alkali. The properties of silicon metal and germanium, lead, tin similar, with semiconductor properties.
Silicon has two allotropes. One is a dark brown amorphous powder, which is active and can burn in the air. The other is a stable crystal (crystalline silicon). Common silica and quartz are used in glass and other building materials, while high-quality quartz is used in alloys, metals and single crystals. Silicon metal (Si) is the industrial purification of elemental silicon, a large number of smelting into ferrosilicon alloy as alloy elements in the steel industry, in many kinds of metal smelting as a reducing agent. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material of ultra-pure silicon in electronic industry. The electronic devices made of ultra-pure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long life.
Through the introduction of the above information, we understand a part of the information about silicon metal, but because of the silicon metal ground into powder, it became silicon metal powder, so the composition of silicon metal powder and silicon metal is the same, but the physical form is not the same. It can also be said that understanding silicon metal is equal to understanding silicon metal powder. Our company provides metal silicon powder for a long time, the quality is qualified, the service is thoughtful, the price is reasonable, if you want to buy, welcome to contact with my company.
