About Silicon

Silicon is a typical example of metalloid, or the substance which looks like metal but does not have its properties. Its name came from the Latin word for flint, and in its pure form it looks like dark-blue metal. There is abundance of this chemical element on our planet, i.e. we can see it in the form of sand on beaches, or in the forms of various silicates. Silicon is considered to be one of the most useful metals for humanity since its alloys and chemical compounds have a large variety of useful properties. They are used, for example, for producing engines, transformers, various tools, popes, elements of roofs and windows, etc. Pure silicon is used for producing glass. As a very good semi-conductor, silicon is used for producing microelectronics, especially computers, laptops, etc.
