Characteristics:
Silicon metal powder, is silver grey or dark grey powder with metal luster. With high melting point, good heat resistance, and high resistivity and anti-oxidation, it is an indispensable raw material for many high-tech industries, called "industrial monosodium glutamate"used as the indispensable basic raw materials of a lot of high-tech products.
Application
1). Industrial silicon metal powder is widely used for refractories and powder metallurgy to improve thermostability, wear resistance and inoxidizability of products. Its products are widely used in steel furnaces, kilns and kiln furniture.
Silicon powder: enhancing the performance of your products
Silicon Metal is typically produced in a size of 0-100 mm, but for most applications further size reduction is required. The optimum particle size depends strongly on the final application. That means in many cases, some optimization work is required to find the most cost competitive solution. Silicon metal powder is produced by crushing, milling and classifying silicon material to obtain the required particle size.
Silicon Metal powder can be produced with a top cut for customers that only need to control the amount of coarse particles. It can also be produced with a top and bottom cut for customers that need to control both 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 that cannot accept any at all contamination from the milling media.
Micronized silicon with top cut can be supplied with a top cut of 6 microns and up. Silicon with bottom and top cut can be supplied with a bottom cut of very few microns and up. The cost will depend largely on production speed and yield.
A raw material that enables a vast range of customers to achieve their goals
Chemsize offers a range of metallurgical silicon powders that are carefully selected, crushed, milled to customer specifications and needs. Different purities and sizes are therefore available, to satisfy customer processing requirements and application needs. Products with customized chemistry and sizing can be produced on request.
Our vast range of products to solve customer requirements
Our silicon powder products include follows spec products, the latter produced using a proprietary hydrometallurgical process.
high purity Silicon metal Powder is with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range.
Silicon metal powder Synonyms are Silicon particles, Silicon microparticles, Silicon micropowder, Silicon micro powder, Silicon micron powder, Silicon submicron powder, Silicon sub-micron powder
