Applications

1. Industrial silicon granule & powder is widely used in the production of refractory materials and metallurgical applications due to its high temperature resistance, wear resistance, and oxidation resistance. Some examples of its application are furnace walls, kilns, and kiln furniture.

2. In organic silicon chemical operations, granular & powder silicon metal is a base material used in the synthesis of organic silicon products. It is often used to manufacture silicon monomers, silicone oils, and silicone rubber preservatives. As an additive, this product provides a significant increase in temperature resistance, electrical insulation, corrosion resistance, waterproofness, and many more highly valuable properties. 3. Some of the more valuable applications of silicone metal involve using silicon wafers to produce integrated circuits and other electronics components. The granule & powder undergoes a drawing process, turning it into monocrystalline silicon wafers. High-tech industries are essentially driven by silicon. 4. In the metallurgical casting industry, industrial silicon metal is an additive for nonferrous alloys and alloying agents in silicon steel in order to greatly enhance the hardness of the finished steel products. Silicon granules are also used as a metal reducing agent for modern ceramic alloys, providing additional hardness and heat resistance.

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.
