Product Description

Industrial Silicon Metal Powder



 

Industrial Silicon Metal Powder

 

Characteristics: Silicon metal powder is a silver grey or dark grey powder with a metal luster. It has a high melting point, good heat resistance, high resistivity, and anti-oxidation properties, making it an essential raw material for various high-tech industries.

 

Applications:

 

1. Widely used in the production of refractory materials and metallurgical applications for high temperature, wear, and oxidation resistance.


2. Base material for organic silicon products synthesis, providing increased temperature resistance, electrical insulation, and corrosion resistance.


3. Utilized in the production of integrated circuits and electronics components.


4. As an additive in metallurgical casting to enhance the hardness of finished steel products.


5. Used in refractories and powder metallurgy to improve thermostability, wear resistance, and inoxidizability of products.


 

 

Additional Applications:

 

• Basic material for organosilicon polymer synthesis.


• Manufacturer of trichlorosilane and polysilicon for hi-tech fields.


• Non-iron-based alloy additives and silicon steel alloying agent in metallurgy and foundry industry.


• Production of silica sol.


• Customizable particle size range based on customer needs.

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.

 

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 spec products produced using a proprietary hydrometallurgical process.

 

• High purity Silicon metal Powder: Ideal for use in preparation of sputtering targets, Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD) processes, water treatment, fuel cell, and solar applications.


• Nanoparticles: Produce very high surface areas, available in various particle sizes including nanoscale range.


 

 

Synonyms for Silicon metal powder include Silicon particles, Silicon microparticles, Silicon micropowder, Silicon micro powder, Silicon micron powder, Silicon submicron powder, Silicon sub-micron powder.
