JQ-900 is a kind of large-scale float-zone monocrystalline silicon furnace with the characteristic of high-reliability, high-precision and high- automation which integrates optic, mechanic and electronic together. The performance of the equipment has reached the international advanced level of similar products. It mainly produces large scale FZ monocrystalline silicon of 6-8 inch. The maximum length of the FZ monocrystalline silicon is 2500mm and the highest purity is 99.99999999%.The FZ monocrystalline silicon wafers are available for the sophisticated fields such as IGBT, SCR, infrared detector, aerospace and navigation. Furthermore, with the high photoelectric conversion efficiency of 23%, we can attempt boldly to use it on the photovoltaic industry.
