High-purity industrial silicon
Industrial silicon, also known as silicon metal, is a silicon element smelted in the ore furnace with silica and carbonaceous reducing agent, with the main component as silicon element of about 98%, and is the main raw material of PV crystalline silicon.
In April 2022, Shangji Automation invested in creating a production line of “high-purity industrial silicon + high-purity crystalline silicon” with advanced global technology, low comprehensive energy consumption, and excellent quality, which will be completed and put into operation in 2023.
Advanced “high-temperature denitration” eco-friendly technology will be adopted in the production process, significantly reducing nitrogen oxide emissions, superior to the environmental protection index requirements of the state and autonomous regions, ahead of peer companies.
In the meantime, regarding electric power which accounts for the highest proportion of industrial silicon production cost, the project will be powered by 60% “green electricity”, reducing the total energy consumption index.
