Product Description

Industrial Silicon Metal Powder

Industrial Silicon Metal Powder

Characteristics:

Silicon metal powder is a silver-grey or dark-grey powder with a metallic luster. It has a high melting point, excellent heat resistance, high resistivity, and anti-oxidation properties. Often referred to as the "industrial monosodium glutamate," it is a crucial raw material for various high-tech industries.

Applications:

1. Used in the production of refractory materials and metallurgical applications for its high temperature resistance, wear resistance, and oxidation resistance. Applications include furnace walls, kilns, and kiln furniture.


2. Base material for organic silicon products, such as silicon monomers, silicone oils, and silicone rubber preservatives, providing enhanced temperature resistance, electrical insulation, corrosion resistance, and waterproofing properties.


3. Utilized in the production of integrated circuits and electronics components through the manufacturing of silicon wafers, essential for high-tech industries.


4. Additive for nonferrous alloys and silicon steel in metallurgical casting to improve hardness. Also used as a metal reducing agent for ceramic alloys.


5. Widely used in refractories and powder metallurgy to enhance thermostability, wear resistance, and inoxidizability of products, commonly found in steel furnaces and kiln furniture.

Our Advantages

Silicon Powder: Enhancing Your Products

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. 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 contamination from the milling media.

Chemsize offers a range of metallurgical silicon powders that are carefully selected, crushed, milled to customer specifications and needs. Different purities and sizes are available to satisfy customer processing requirements and application needs. Products with customized chemistry and sizing can be produced on request.

Key Features:

• High purity Silicon metal Powder


• Customized chemistry and sizing


• Wide range of particle sizes available


• Suitable for various applications including sputtering targets, CVD, PVD, water treatment, fuel cells, and solar applications

Product Specifications:

• Particle sizes: - 325 mesh, - 100 mesh, 10-50 microns, submicron (< 1 micron)


• Available in nanoscale range


• Synonyms: Silicon particles, Silicon microparticles, Silicon micropowder, Silicon micro powder, Silicon micron powder, Silicon submicron powder, Silicon sub-micron powder
