Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

EstablishmentPrisonersExpansion: Gusen II and Gusen IIIKillingsMedical ExperimentsForced LaborArmaments ProductionJanuary–May 1945After The WarLocated around three miles away from Mauthausen concentration camp, the Gusen site had attracted the SS because of its proximity to the Gusen and Kastenhof stone quarries. SS authorities purchased land at the site on May 25, 1938. Managers of the SS-owned firm Deutsche Erd- und Steinwerke(DESt-German Earth and Stone Works), which used concentration camp prisoner labor to extract and finish construction materials at Mauthausen, established next to the “Wiener Graben” stone quarry in 1938, deployed a forced labor detachment from Mauthausen on a daily basis to the Gusen quarries beginning in 1938. Tiring of marching the prisoner detachment three miles to the Gusen quarries, SS authorities authorized the construction of concentration camp Gusen in late 1939. During the winter of 1939–1940, German, Austrian, and Polish concentration camp prisoners from Mauthausen constructed the camp and prisoner barracks.

BackgroundEmigration from ViennaKristallnacht in ViennaDeportations from ViennaForced Labor in ViennaLiberationVienna was the capital of a large multi-national empire under the German-speaking Habsburg dynasty for five centuries. After 1918, following World War I, Vienna became the capital of the small Republic of Austria. Vienna's population of 1.9 million was 28 percent of the countryentire population in 1934. In 1938, some 170,000 Jews lived in the city, as well as approximately 80,000 persons of mixed Jewish-Christian background. Including converts from Judaism, the Viennese Jewish population may have been as high as 200,000, more than 10 percent of the cityinhabitants. Vienna was an important center of Jewish culture and education. The city was also a center of Zionist thought and Theodor Herzl, the father of Zionism, had studied at the University of Vienna. Many Viennese Jews were well-integrated into urban society and culture. Jews made up significant percentages of the citydoctors and lawyers, businessmen and bankers, artists and journalists.

Were There Concentration Camps in Austria? - WorldAtlas

About The Concentration Camps in AustriaHistory of The Concentration Camp ComplexTreatment of PrisonersWhen Adolf Hitler and his Nazi Party Annexed Austria in March 1938, his aim was to take full control of the country and make it part of Greater Germany. Immediately after the annexation of Austria, Nazi Germany erected the Mauthausen concentration camp in Mauthausen and several other subcamps throughout the country. The concentration camps operated from 1938 until the end of World War II in 1945. The prisoners at the concentration camps in Austria, like most Nazi prisoners in Germany, were forced into slavery under poor conditions that led to the death of many of them. Mauthausen was the last Nazi Germany concentration camp to be liberated by the Allies. As of January 1945, the camp had over 85,000 prisoners. Although the number of deaths is unknown, several sources place it as 122,000-320,000 people for the whole Mauthausen-Gusen concentration camp complex.Get price
