As is well known, metal silicon powder is made by grinding metal silicon, so we can say that metal silicon is an important raw material for metal silicon powder. Metal silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product made by melting time and coke in an electric furnace. The main component silicon content is about 98%, and the remaining impurities are iron, aluminum, calcium, etc. According to the content of iron, aluminum, and calcium in metal silicon, it can be divided into many different brands. In addition, metal silicon also has many additional products, such as silicon powder, side skin silicon, black skin silicon, metal silicon slag, etc. Silicon micro powder, also known as silicon powder, silicon powder, or silicon powder, is widely used in the refractory and concrete industries. Insoluble in acids at room temperature, soluble in alkalis. Silicon metal has properties similar to germanium, lead, and tin, and has semiconductor properties.
Silicon has two types of allotropes, one is a dark brown amorphous powder, which is active and can be burned in air. Another type is stable crystal (crystalline silicon) silica, which is commonly used for glass and other building materials, while high-quality silica is used for manufacturing alloys, metals, and single crystals. Silicon metal is an industrial purified element of silicon. As an alloy element in the steel industry, it is widely used for smelting ferrosilicon alloys and is also a reducing agent for smelting various metals. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material for ultrapure silicon in the electronic industry. Electronic devices made of ultrapure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability, and long service life.
Through the introduction of the above information, we have gained some information about metallic silicon. However, when metal silicon is ground into powder, it becomes metal silicon powder, so the composition of metal silicon powder is the same as that of metal silicon, but the physical form is different. It can also be said that understanding metallic silicon is equivalent to understanding metallic silicon powder.
