Adsorption Behavior of Ni-Doped ZnO Monolayer upon SF6 ...· In this article, Ni-doped ZnO (Ni-ZnO) monolayer is proposed as a potential sensing material for detection of two SF6 decomposed components (namely, SO2 and SOF2), based on the density functional theory (DFT) method, to monitor the operation status of SF6 insulation devices in the power system. The Ni-doping effect on the physicochemical properties of the pure ZnO monolayer is first …

Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluidgasbanor.com/english/products.htmProducts SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).
