Silicon metal powder is a powdery substance made from ground lumps of silicon metal. Depending on the application, the particle size of the silicon powder may vary. Depending on the amount of impurities in the silicon metal powder, the common ones are silicon metal 441 powder, silicon 553 powder and so on.
The main component contained in silicon metal powder is crystalline silicon. It is initially in the form of lumps. The color is also relatively stable. After a series of crushing or grinding, it becomes silicon powder.
Silicon metal powder is divided into metallurgical grade silicon metal powder and chemical grade silicon metal powder. Our common 553/441 and so on belong to metallurgical grade silicon metal powder. Chemical grade silicon metal powder is usually used in the production of organic silicon and polysilicon. The purity of chemical silicon powder is higher.
Globally, the consumption of metallurgical silicon is higher than chemical silicon. However, with the continuous development of science and technology, the use of chemical silicon powder in the production of silicone and semiconductors is expanding. It is widely used in the production of silicone monomers. Or it is used in the production of polymer silicone oil, silicone rubber, building anticorrosive silicone resin, waterproofing agent and so on. As the core of integrated circuits, more than 95% of electronic components are made of semiconductor silicon. Therefore, chemical grade silicon metal powder is more and more widely used.
