Silīcijs metāls, 

The silicon metal can be supplied as silicon chunks or silicon powder in specific mesh ranges to meet individual customer requirements. Silicon is technically a metalloid due to its intermediate metal and non metal characteristics. It is a grey metallic material which is very hard and brittle. The main grade categories of silicon metal are: Chemical, Metallurgical and High Purity. The Chemical silicon grade is used for the production of silicone compounds. These compounds are the raw material for many industrial and consumer products including rubber, adhesives, lubricants and cosmetics. Metallurgical silicon grade is an additive for the production of non ferrous alloys, particularly aluminium-silicon. The silicon metal enhances the alloy performance in applications for the aerospace, automotive and construction industries. High Purity silicon is used in the production of silicon wafers used as photovoltaic and electronic semiconductors.
