Sulfur hexafluoride | F6S - PubChem

Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (Sulfr hexafluoride has an estimated lifetime in the atmosphere of between 800 and 3,000 years).Get price

Using insulating gas Gas In Medical Applications

Sulphur Hexafluoride (sf6 gas) is a man-made gas comprising of one sulphur and six fluoride atoms. Key properties of the gas are that it is extremely chemically stable and has a relatively high density. Commonly used within the electrical industry as an insulating medium, the properties of the gas also make it highly suitable for use in ophthalmology.Get price

Comparing the densities of Australian, European, Canadian

Why Population Weighted Density?Defining CitiesHow Much Diversity Is There in Urban Density?Do Many People in European Cities Live at Typical Australian Suburban densities?How Different Is Population-Weighted Density from Regular Density?So What Does The Density of These Cities Look Like on A Map?What Does This Mean For Transport?All The Density MapsAs discussed in previous posts, population-weighted density attempts to measure the density at which the average city resident lives. Rather than divide the total population of a city by the entire city area (which usually includes large amounts of sparsely populated land), population weighted density is a weighted average of population density of all the parcels that make up the city. As I’ve shown previously, the size of the parcels used makes a big difference in the calculation of population-weighted density, which makes comparing cities difficult internationally. To overcome the issue of different parcel sizes, I’ve used kilometre grid population data that is now available for both Europe and Australia. I’ve also generated my own kilometre population grids for Canadian and New Zealand cities by proportionally summing populations of the smallest census parcels available. Some measures of density exclude all non-residential land, but the square kilometre grid approach means that p...Get price
