The application of silicon
Application of silicon Silicon atomic structure determines the silicon atom has a certain electrical conductivity, but because there is no obvious free electron in silicon crystal, the electrical conductivity is not as good as metal, and increases with the rise of temperature, so it has semiconductor properties. In the world, commercial silicon is usually divided into silicon metal and silicon semiconductor. The silicon metal of Weihai Harmony silicon industry is mainly used to manufacture polycrystalline silicon, monocrystalline silicon, silicon aluminum alloy and silicon steel alloy compounds. Semiconductor silicon is used to make semiconductor devices. Generally speaking, silicon is mainly used in the manufacture of high purity semiconductors, high temperature resistant materials, optical fiber communication materials, organic silicon compounds, alloys, etc., widely used in aerospace, electronics and electrical, construction, transportation, energy, chemical, textile, food, light industry and other fields, medical, agricultural and other industries.
High purity semiconductor
Weihai Harmony silicon industry pointed to integrated circuits. High purity monocrystalline silicon is an important semiconductor material. It can be made into diodes, transistors, thyristors, and various integrated circuits (including the chips and cpus in people's computers). It can also be made into solar photovoltaic cells that convert radiant energy into electricity.
High temperature resistant material
To make cermet composite materials. This material inherits the advantages of metals and ceramics and compensates for their disadvantages. High temperature resistance, high toughness and cutting ability.
Fiber optic communication material
High transparent glass fiber is an important fiber communication material. This communication mode replaces the heavy cable, and has the advantages of large communication capacity, no electromagnetic interference, no fear of eavesdropping, and high confidentiality. Fiber optic communication has revolutionized human life.
Organosilicon compound
The organic compounds of silicone gun silicon combine the excellent inorganic properties of silicon with the properties of organic materials, making silicon compounds unique and opening up a new field. With low surface tension, low viscosity temperature coefficient, high compressibility, high permeability of basic properties, with high and low temperature resistance, electrical insulation, oxidation resistance, weather resistance, fire resistance, hate water, corrosion resistance and other excellent characteristics, non-toxic tasteless, physiological inertia. Mainly used for sealing, bonding, lubrication, coating, surface activity, demoulding, defoaming, defoaming waterproof and moistureproof, inert filling, etc., with the continuous growth of the number and variety of silicone, the application field is expanding. Organic silicon has become an important product system in the field of new chemical materials. Weihai Harmony silicon industry proposed that many silicone varieties are irreplaceable and indispensable to other chemicals.
Silicone materials can be divided into silane coupling agent (organic silicification reagent), high temperature vulcanized silicone rubber, liquid silicone rubber, silicone oil (silicone grease, silicone emulsion, silicone surfactant), silicone resin, composite materials, etc. For example, organic plastics can be used to make excellent tarps, subway walls can be sprayed with silicone to solve water seepage problems, and antiquities and sculptures can be painted with silicone compounds, weihai harmony said. Silicone oil is a good lubricant. Silicone rubber can be used as insulating material or medical polymer material. Influenced by the distribution and demand of China's textile, electronics, medicine, daily chemicals and other terminal industries, silicone rubber accounts for half of the downstream silicon products.
