Silicon metal powder is primarily used in the following industries: the organosilicon industry, the semiconductor and photovoltaic industries, and the metallurgical industry. It also serves important applications in ceramics, coatings, and other fields.
1. Organosilicon Industry
This is the largest application area for metallic silicon powder, consuming approximately 70% of global metallic silicon production.
Metallic silicon powder reacts with methyl chloride to produce methylchlorosilane.
Methylchlorosilane serves as the core raw material for manufacturing organosilicon monomers, which are further processed into organosilicon products like silicone rubber, silicone oil, and silicone resin.
These organosilicon products are widely used in electronics, construction, automotive, and medical industries-for instance, as high-temperature resistant sealants or as smoothing agents in cosmetics.
2. Semiconductor and Photovoltaic Industries
In high-tech fields, high-purity metallurgical silicon powder is an indispensable material.
Semiconductor Industry: Metallurgical silicon powder with a purity of 99.999% (5N) or higher undergoes processes such as crystal pulling and wafering to produce monocrystalline silicon wafers, which serve as substrate materials for chip manufacturing.
Photovoltaic Industry: Metal silicon powder with a purity around 99.99% (4N) can be used to produce polycrystalline or monocrystalline silicon, which is then processed into photovoltaic cells-the core raw material for solar power generation.
3. Metallurgy and Other Fields
Metal silicon powder also has extensive applications in traditional industries and new materials sectors.
Metallurgy: It serves as a deoxidizer and alloying agent in steel or non-ferrous metals, enhancing material strength and corrosion resistance. Additionally, silicon metal powder is a raw material for producing silicon-aluminum and silicon-calcium alloys.
Ceramics Industry: High-purity silicon metal powder is used to manufacture advanced ceramic materials such as silicon nitride ceramics and silicon carbide ceramics. These materials exhibit high strength, high-temperature resistance, and wear resistance, making them suitable for high-end mechanical components.
Other Fields: Silicon metal powder serves as a filler in coatings and rubber, improving product wear resistance and aging resistance. It is also used in the production of silicon-based composite materials for applications in aerospace and other sectors.
