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 due to its high temperature, wear, and oxidation resistance.


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


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


4. As an additive in nonferrous alloys and silicon steel to improve hardness in metallurgical casting.


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


6. Applied in the organosilicon chemical industry for synthesizing silicon monomers and improving product properties.


7. Essential raw material for manufacturing integrated circuits and electronic components in the hi-tech fields.


8. Used as non-iron-based alloy additives and silicon steel alloying agents to improve hardenability in metallurgy and foundry industry.


9. For the production of silica sol and various particle size ranges available 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 further size reduction is often necessary for various applications. The particle size optimization is crucial for achieving the best results, requiring some customization for cost-effective solutions. Silicon metal powder is meticulously produced through crushing, milling, and classifying silicon material to achieve the desired particle size.

Our micronized silicon powder can be tailored with top cuts for controlling coarse particles or with both top and bottom cuts for managing fine particles. The particle shape can also be adjusted to some extent during micronizing. We offer contamination-free micronizing for customers with strict purity requirements.

Chemsize provides a range of metallurgical silicon powders with different purities and sizes to meet diverse processing and application needs. Customized products with specific chemistry and sizing can be developed upon request.

Key Features:

• High purity Silicon Metal Powder with small grain sizes for sputtering targets and various deposition processes.


• Available in different particle sizes, including nanoscale options, for high surface area applications like water treatment, fuel cells, and solar technologies.


• Produced using a proprietary hydrometallurgical process for superior quality.

Product Specifications:

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