Silicon metal 2205

Silicon metal 2205, also known as crystalline silicon or industrial silicon, silicon metal 2205 is made of quartz and coke in the electric furnace smelting products, silicon metal has become a primary product of many emerging energy markets. In recent years, with the increasing demand for the quality and variety of silicon metal products, new requirements have been put forward for the smelting of silicon metal.

In the traditional metal silicon 2205 smelting process, there are mainly hydrometallurgy method (pickling, solution corrosion), slag treatment method, powder metallurgy method, gas blowing method, energy beam (electron beam, other ion beam) method, directional solidification method, silicon alloy method, high purity raw material method, sodium reduction method, thermite reduction method and electrolysis method. The smelting method of metal silicon can not remove a variety of impurities at the same time, and often can only be effective for some impurities, which can not meet the requirements of metallurgical grade high purity silicon, and then affect the quality of metal silicon products.
