Products Description
Silicon metal 2202 is a kind of industrial purified elemental silicon, and its main component silicon content is about 98% (in recent years, the silicon containing 99.99% is also listed in metallic silicon), and the rest impurities are iron, aluminum, calcium and so on.
Silicon metal 2202 is mainly used for producing silicone, preparing high-purity semiconductor materials and preparing alloys with special purposes. For example, it can be used to produce silicone products such as silicone rubber, silicone resin and silicone oil, and can also be used to manufacture high-purity semiconductors. It can also be used as non-iron-based alloy additives and silicon steel alloying agents in the metallurgical casting industry.
The production process of silicon metal 2202 mainly includes the processes of extracting silicon ore from ore or ore sand, crushing, grinding, beneficiation, etc, then mixing with coke and putting it into a high-temperature electric furnace for smelting, and finally obtaining metallic silicon 2202 with high purity through cooling, separation, refining and other treatments. In the process of processing, casting, pressing, extrusion and other processing techniques can also be carried out according to specific needs to make products with required shapes.
Silicon metal 2202 is an important raw material for manufacturing semiconductor materials. After refining and purification, high-purity silicon materials can be obtained, which can be used to manufacture semiconductor devices, such as integrated circuits, solar panels, LEDs and other electronic devices. Its high purity and good electronic properties make silicon metal 2202 widely used in the electronic industry. Silicon metal 2202 is also one of the main raw materials for solar cells. Silicon materials for solar panels can be prepared by specific technological treatments. The high purity and good photoelectric properties of metallic silicon 2202 make solar cells have higher conversion efficiency and longer service life.
