Mixutures of insulating gas with nitrogen or tetrafluoromethane as

sf 6 Mixtures. In addition to the use of sulphur hexafluoride (SF 6) as a single gas, mixtures of SF 6 with nitrogen (N 2) or tetrafluoromethane (CF 4) are also used as insulating or test gas. The IEC recommends a purity of SF 6 of at least 99.7 vol.-% for the use in mixtures. SF 6 gas reconditioned or treated by DILO clearly meets these criteria and is therefore suitable for the use in gas mixtures.Get price

gaz sf6 gas handling - DILO

However, DILO separating units allow the SF 6 gas mixture to be purified to the extent that it even meets the standards of IEC 60376 (directive for new SF 6 gas technical quality) with regard to moisture, SF 6 percentage and decomposition products (SO 2).Get price

Alternatives for insulating gas | 2020 | Siemens Energy Global

Another option are certain fluorinated gas mixtures that also have less greenhouse gas potential than SF 6. For example, the Zurich-based energy supplier EWZ has been using such a solution since 2015, and in 2019 a 380 kV plant was erected in Bavaria, Germany. However, these gas mixtures lose their effectiveness at very low temperatures.Get price

Selective Dry Etching of GaN Over AlGaN in BCL3/sf 6 Mixtures

Inductively coupled plasma (ICP) etching of GaN with high selectivity over Al. 22 Ga. 78 N in BCl 3 /SF 6 mixtures has been studied. Selectivity and surface morphology were investigated over a wide range of pressures (3.75 37.5mTorr), RF powers (30 120 W), ICP powers (100 400 W), and SF 6 /BCl 3 ratios (0.1 0.7). Higher pressures, lower dc biases, and higher SF 4 /BCl 3 ratios increased the GaN to AlGaN selectivity.Get price
