What are the uses of silicon in silicon balls? Let's learn:
(1) Pure monocrystalline silicon is an important semiconductor material: a small amount of group IIIA elements are doped into monocrystalline silicon to form p-type silicon semiconductor; Adding a small amount of Group VA elements to form n-type and p-type semiconductors, combined together, can be made into solar cells to convert radiant energy into electrical energy. It is a promising material in the development of energy;
(2) Cermets and important materials for space navigation: cermets and metals are mixed and sintered to make cermets composite materials. It is resistant to high temperature, rich in toughness and can be cut. It not only inherits the respective advantages of metals and ceramics, but also makes up for their congenital defects;
(3) Optical fiber communication, modern communication means: high transparency glass fiber is drawn with pure silica. The laser is transmitted forward through multiple total reflections in the path of glass fiber, replacing the bulky cable. Optical fiber communication capacity is high. A glass fiber as thin as a hair can transmit 256 calls at the same time.
