Furthermore, the group offers different engineering services for other complex production processes in the chemical industry Large scale production of silicon is done by reduction of quartz with carbon. The necessary high temperatures of about 2000 °C are processed by an electric arc in a reduction furnace. A mixture of quartz and different carbon materials (coal, coke or charcoal) is continuously fed into the furnace Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth's crust (behind only oxygen) and the eighth-most common element in the universe. Nearly 30 percent of the weight of the earth's crust can be attributed to silicon

The silicon production process is the starting point for all of these products. Silicon or ferrosilicon is produced in large electrical furnaces from quartz and carbon materials like charcoal and coal.
