The industrial extraction of silicon requires a carbothermal reduction of quartz (SiO2) within an electric arc furnace at temperatures of more than 2,000 °C. This process yields a material called silicon metal with a purity of at least 98.5 %.
Across the globe, there is a demand for approximately 2.7 tons of silicon metal. Silicon serves as an alloying element in aluminium and ferro-alloys, as raw material for the fabrication of silicones and chemical products, or as a basic resource for solar cells and computer chips.
Within our increasingly electrified world, silicon metal plays an increasingly vital role in fields such as construction, battery systems, and automotive technology.

Silicon Provided by EKC.AG: Industrial Sectors and Usage
Silicon is the number-one raw material of the solar age in the 21st century. More than 80 to 85 % of all solar cells produced worldwide contain silicon metal. The availability of silicon is considered virtually endless. After all, 60 % of the earth’s crust consist of silicon dioxide (SiO2), also known as ”quartz sand“ or simply “sand.” This makes silicon the second most common element on earth. Nevertheless, extracting silicon requires an extremely high energetic and technical effort.
Silicon metal serves various purposes in chemical industries. For example, it can be used as a base material for the production of silanes and silicones in coatings, resins, varnishes, etc. It furthermore helps to produce high-strength alloys as an alloying element in ferro-alloys and aluminium, which are needed for castings or lightweight materials in the automotive industry. Of course, silicon metal also constitutes the main raw material (i.e. the base material) necessary to produce highly purified silicon for solar cells (photovoltaic modules) or computer chips. The resulting by-product microsilica is put to use in the construction materials industry.
