Product Description

Industrial Silicon Metal Powder Description



 

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 high temperature, wear, and oxidation resistance.


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


3. Utilized in the production of integrated circuits and electronics components, driving high-tech industries.


4. Additive for nonferrous alloys and silicon steel in metallurgical casting to improve hardness.


5. Widely used in refractories and powder metallurgy to enhance thermostability, wear resistance, and inoxidizability.


6. Basic material for organosilicon polymer synthesis, improving product properties like thermostability and corrosion resistance.


7. Applied in the production of trichlorosilane and polysilicon for hi-tech fields and integrated circuit manufacturing.


8. Used as non-iron-based alloy additives and silicon steel alloying agent in metallurgy and foundry industry.


9. Key component for producing silica sol and meeting various particle size requirements.

Our Advantages

Silicon Powder: Enhancing Your Product Performance



 

Silicon Powder: Enhancing Your Product Performance

 

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 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.

 

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.
