Silicon metal is obtained from silica found in quartz, through reduction in submerged arc electrical furnaces, which could exceed 3.000o C, using charcoal and planted forest wood chips as reductant.

Silicon metal is a grey and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, and is mainly used as an additive for non-ferrous alloys. Silicon metal is produced from quartz and coke in an electric furnace, and the content of the silicon element is about 98% (in recent years, with a content of 99.99%, Si is also called silicon metal), and the other impurities are mainly iron, aluminium, calcium, and so on. The classification of metallic silicon is according to the content of iron, aluminium, and calcium; silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.


Electronics: Silicon metal is the cornerstone of the electronics industry. It forms the basis of integrated circuits, microchips, transistors, and other essential components that power our digital world.

Solar Energy: Silicon's photovoltaic properties make it an indispensable material in solar cell production. It captures and converts sunlight into electricity, enabling clean and renewable energy generation.

Construction and Infrastructure: Silicon compounds are employed in construction materials like concrete, glass, and ceramics, enhancing their durability and stability.

Medical and Biotechnology: Silicon wafers play a critical role in medical imaging technologies like X-rays and MRI machines. Silicon's biocompatibility also makes it suitable for implantable medical devices.
