Discovery of Silicon powder

What is Silicon powder?

Silicon powder can be produced with a top cut for customers who only need to control the coarse particles. It can also be produced with a top and bottom cut for customers who need to control the amount of coarse and fine particles. The shape of the particles can also, to some extent, be altered by the technology used at the micronizing stage. Contamination-free micronizing is also possible for customers who cannot accept all contamination from the milling media. The optimum particle size depends strongly on the final application. This means that, in many cases, some optimization work is required to find the most cost-competitive solution. Silicon powder is produced by crushing, milling, and classifying silicon material to obtain the required particle size.

Use of Silicon powder

Silicon is a semiconductor material that makes semiconductor devices, solar panels, optical fibers, and integrated circuits. It can also be used as alloys (such as ferrosilicon alloys) for automotive and mechanical parts, used with ceramic materials in cermet, and used in manufacturing glass, concrete, brick, refractory materials, siloxane, and silane. With an iron union, it can become siliceous steel; this is a kind of wear-resisting steel piece commonly used on all sorts of tools. In addition, silicon is one of the main components of stainless steel, which makes stainless steel wear resistant.

Discovery of Silicon powder

Silicon was discovered in 1824 by J.J. Berzelius in Stockholm, Sweden. After carbon, silicon is the most abundant element on earth, the abundance being 277,000 ppm. It is generally present as a silicate, found in many rocks, clays, and soils. Silicon is obtained by reducing silica (sand, SiO₂) with carbon. Further purification of the element for applications requiring high-purity material (e.g., semiconductor devices) is achieved by zone refining, the resulting purity being better than 1:10⁹. Silicon exists in two allotropic forms; brown silicon is a powder, whereas crystalline (metallic) silicon is grey, and the latter is more widely used. Bulk silicon is unreactive towards oxygen, water, and acids (excluding HF) but is soluble in hot alkalis. Silicon has many applications in various industries; for example, ultra-high purity silicon is used in the semiconductor industry due to its semiconducting properties. Silicon is also used as an alloying element in certain alloys (e.g., ferrosilicon, an alloy of iron and silicon, which is used to introduce silicon into steel and cast iron). It is also used in the manufacture of glass.

Price of Silicon powder

Silicon powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Silicon powder. A large amount of large amount will be lower. The Price of Silicon powder is on our company's official website.
