-Metal silicon can be used as a casting material to improve the toughness and thermal fatigue resistance of castings and reduce casting defects and deformation. Steel-making is an area where silicon plays a critical role since it has a great promotion effect on tempering the functions of metal products in the steel tempering process. Most cast aluminum alloys contain silicon because the silicon could also act as an alloying agent in aluminum casting as well.
-Metal silicon can be made into sorts of types and uses of semiconductors, such as transistors, integrated circuits, etc. It is crucial for its indispensability as a raw material for solar products which is an energy alternative after coal and oil. Integrated circuits made of silicon are widespread applications. Various electronic products such as personal computers and handsets require the support of integrated circuits.
-The applications of metal silicon are mainly silicone, polysilicon, and aluminum alloys. Silicone has the highest requirements for metal silicon, which requires chemical grade, and the corresponding model is 421#. Followed by polysilicon, the commonly used are 553# and 441#. Aluminum alloy requirements are minimal.
-Silicon is the raw material for ultrapure silicon in the electronics industry. Electronic devices made of ultrapure semiconductor single crystal silicon have the advantages of small size, lightweight, good reliability, and excellent durability.
-Metal silicon can be used as a casting material to improve the toughness and thermal fatigue resistance of castings and reduce casting defects and deformation.
