Hello all, I was looking up SF6 in my Merck Index and found something that caught my eye. I follows: "At 25 Deg. and 1 ATM 0.297 ml SF6 dissolves in 1.0 ml transformer oil." Now, it would seem to me that oil with such an additive would indeed be interesting, not to mention an economical way to use the stuff. Anybody hear of such stuff? David Trimmell <dwt-at-efn-dot-org>
