Introduction
Silicon is a very important element in the manufacturing industry. It is primarily used in the production of semiconductors, which are essential for modern electronics. Other uses for industrial silicon are as a reinforcement in composites, as a filler for rubbers, as a negative electrode in lithium-ion batteries and for specialized catalysts.
History
Industrial silicon was first discovered in 1787 by the Swedish chemist, Johan Gadolin. For many years, it was viewed as having little industrial use, and it was not until the discovery of its electrical properties in 1833 by Michael Faraday that it began to be seen as an important material. By the beginning of the twentieth century, the use of industrial silicon was becoming more widespread, particularly after a process was discovered that allowed its purification. In the last few decades, the uses of industrial silicon have increased exponentially, leading to its current status as a major industrial material.
Production
There are several ways in which industrial silicon is produced, although the most common method involves the reaction of silica with carbon. This can be done with ferrosilicon, which consists of finely divided silicon particles with a high amount of impurities, or with purer forms such as metallurgical-grade silicon. In either case, this reaction creates a highly purified form of silicon known as silicon metal. This silicon metal is then further processed to create a variety of different forms, such as uranium silicide, an alloy of uranium and silicon which is used as an alloying agent in the production of stainless steel.
Applications
Industrial silicon is used in a wide range of applications, including electronics, metallurgy and manufacturing. It is commonly used as a base for semiconductor products, such as transistors, diodes and integrated circuits. Silicon crystals are also used in the creation of solar cells and solar thermal energy panels, due to their ability to absorb light and convert it into energy. In addition, silicon is used in the production of ferrosilicon alloys, which are in turn used in the production of steel and other alloys. It is also commonly used in the production of silicones, silicone oil and rubber.
Conclusion
Industrial silicon is a very important material in the manufacturing industry. It is primarily used in the production of semiconductors and other electronics, as well as alloys, silicone and rubber. It has a wide range of uses, both in terms of its electrical and mechanical properties, and its versatility makes it an ideal material for many industrial applications.
