The use of silicon element in silicon balls

1. High-purity single crystal silicon is an important semiconductor material: trace amounts of Group IIIA elements are mixed into single crystal silicon to form p-type silicon semiconductors; trace amounts of Group VA elements are mixed into single crystal silicon to form n-type and p-type semiconductors. Combined together, they can be made into solar cells that convert radiant energy into electrical energy. It is a promising material in developing energy sources.
2. Cermet, an important material for space navigation: Ceramic and metal are mixed and sintered to make cermet composite material. It is high temperature resistant, tough and can be cut. It not only inherits the respective advantages of metal and ceramic, but also makes up for the two. the person’s congenital defects.
3. Optical fiber communication, modern communication method: Highly transparent glass fiber is drawn from pure silica. The laser is transmitted forward through multiple total reflections in the path of the glass fiber, replacing bulky cables. Optical fiber communication has high capacity. A glass fiber as thin as a hair can transmit 256 telephone calls at the same time. It is also free from electrical and magnetic interference and has a high degree of confidentiality.
