Sulfur hexafluoride
Sulfur hexafluoride(SF6) iskar inorganic, mara launi, mara wari, kuma iskar gas mara ƙonewa. Amfani na farko na SF6 shine a cikin masana'antar lantarki azaman matsakaicin dielectric gaseous don nau'ikan wutar lantarki daban-daban, masu juyawa da sauran kayan lantarki, galibi suna maye gurbin masu jujjuyawar mai (OCBs) waɗanda zasu iya ƙunsar PCBs masu cutarwa. Ana amfani da iskar SF6 a ƙarƙashin matsin lamba azaman insulator a cikin iskar gas ɗin canza canjin gas (GIS) saboda yana da ƙarfin dielectric fiye da iska ko busasshiyar nitrogen. Wannan dukiya ta sa ya yiwu a rage girman girman kayan lantarki.
