Plansee supplies suitable tungsten-nickel sputtering targets for manufacturing electrochromic layers in dimmable smart windows. At the same time, we are the only sputtering target manufacturer who covers the entire range from raw material to the finished planar- or rotary target – all production steps are carried out in-house. Our process chain starts with the reduction of ultrapure oxide to metal powder. This is the only way for us to guarantee the highest material purity and an optimal microstructure. An absolute must for a high degree of efficiency – producing uniform erosion rates and high sputtering speeds.
