According to user requirements, we can produce silicon metal powder with mesh sizes ranging from 150 to 325 and support custom production of different contents, offering professional guidance both before and after sales, all at competitive prices for high quality products and services.
What is Silicon Metal Powder?
Silicon metal powder is made by crushing and grinding different grades of silicon metal into powder of various mesh sizes, which is then packaged in bags of different sizes. The production of silicon metal powder first requires workers to select high purity silicon metal, followed by professional laboratory testing to ensure the chemical composition and specifications meet user requirements. The powder is then processed through steps like crushing, screening, grinding, and packaging, with workers strictly adhering to production standards at each stage.
Specifications of Silicon Metal Powder
Similar to Silicon metal, silicon metal powder is graded based on its internal Si content. However, different industries have varying requirements for the mesh size of silicon metal powder, so it’s important to note these differences when purchasing.

Applications of Silicon Metal Powder
- Silicon metal powder has high purity silicon elements and good conductivity, making it widely used in the manufacturing of semiconductor materials, photovoltaic cells, and various electronic components.
- In ceramic production, it effectively enhances the hardness and high temperature resistance of ceramics, resulting in products that are wear-resistant and have a long service life, such as automotive brake pads and ceramic knives.
- Silicon metal powder is often a key raw material in the production of silicates, silicone rubber, and silicone gel, with applications across industries like construction, automotive, and pharmaceuticals.
- Using silicon metal powder in alloy materials can significantly improve mechanical properties, increase hardness and wear resistance, while effectively reducing production costs.
- It is also an important component in the production of refractory materials, particularly silicon carbide refractories, enhancing thermal shock resistance and oxidation resistance.
- In the coatings and plastics industry, silicon metal powder serves as a filler and reinforcement, improving wear resistance, high temperature resistance, and mechanical strength.
High Purity Silicon Metal Powder
Silicon metal powder with Si ≥ 99.9% is referred to as “high purity silicon metal powder.” It is generally made from grades 3303#, 2202#, and 1101# silicon metal, as these grades contain high Si content and have low impurities, making it easier to produce high purity silicon metal powder. High purity silicon metal powder is typically used in the production and application of photovoltaics, semiconductors, and high end aluminum materials. Through purification, high purity silicon metal powder serves as raw materials for silicone oil and silicone rubber and has also been widely applied in industries such as healthcare and construction in recent years.
Advantages of Silicon Metal Powder
Silicon metal powder has good conductivity, facilitating quicker chemical reactions during use, thus increasing production efficiency and reducing costs. Additionally, the rich silicon content in silicon metal powder makes it an essential raw material in many silicon product industries, simplifying production processes and enhancing efficiency. With the growing emphasis on environmental protection, it serves as an important raw material in the semiconductor industry and is widely used across automotive, photovoltaic, semiconductor, and even emerging industries.
