Metallic silicon, also known as crystalline silicon or industrial silicon, has a wide range of uses, mainly including the following aspects:
1. Semiconductor industry: Metallic silicon is an important component of semiconductor materials and is used to manufacture integrated circuits, solar panels, LEDs and other electronic devices. Its high purity and good electronic properties are widely used in the electronics industry.
2. Steel smelting: In the metallurgical industry, metallic silicon is an important alloy raw material. Adding an appropriate amount of it to steel can improve its hardness, strength and wear resistance, and improve physical and chemical properties.
3. Casting industry: Metallic silicon can be used as a casting material to improve the toughness and thermal fatigue resistance of castings and reduce casting defects and deformation.
4. Solar thermal power generation: Metallic silicon is also used in solar thermal power generation. By focusing solar energy on the surface of metallic silicon, light energy is converted into heat energy, and then the heat energy is used to generate steam to drive turbine generators to generate electricity.
5. Nanomaterial preparation: Metallic silicon can be converted into nanoparticles, nanowires or nanofilms through appropriate chemical reactions and processing methods.
6. Other industrial fields: Metallic silicon is also an important raw material for manufacturing silicone products such as silicone oil, silicone rubber, silane coupling agent, and is used to manufacture polysilicon, which is used in solar photovoltaic and semiconductor materials. In addition, metallic silicon is also used to produce trichlorosilane, and can be used to prepare a variety of silicone resin lubricants and waterproof compounds. In terms of thermal insulation materials, microporous calcium silicon thermal insulation materials have excellent characteristics such as small heat capacity and high mechanical strength, and are widely used in various thermal equipment and pipelines. Special calcium silicon materials can be used as catalyst carriers and are widely used in oil refining, automobile exhaust purification and many other aspects.
