Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of Sulfr hexafluorideChemical Properties of gaz sf6 GasElectrical Properties of gaz sf6 Gasinsulating gas or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that insulating gas gas could be used as gaseous insulating material.

Shape and Volume of the Skaergaard Intrusion, Greenland

IntroductionThe Skaergaard IntrusionReinterpretation of The Structure of The Skaergaard IntrusionDiscussionConclusionsThe Tertiary Skaergaard intrusion, southern East Greenland (Wager & Deer, 1939; McBirney, 1996; Irvine et al., 1998), has for decades been the testing ground for models of magmatic differentiation. Despite an abundance of field data, the shape of the magma chamber, its internal structure and the volume relations in the intrusion remain largely hypothetical and inadequate for mass balance calculations and petrogenetic modelling. The need for detailed modelling of the shape and volume of the intrusion as a whole, and of lithological zones in the intrusion, has increased over the last decade, not only for purely academic reasons, but also as a consequence of the identification of major precious metal deposits within the intrusion (e.g. Nielsen & Schønwandt, 1990; Bird et al., 1991; Andersen et al., 1998). The intrusion hosts a potential world-class deposit with 20 million ounces of PGE (mainly Pd) and Au in a 5 m wide stratiform horizon (Nielsen, 2001). Wager & Deer (1939) proposed th...Get price
