what is the chemistry definition for amalgam?
142330
An amalgam is any alloy of mercury. Most metals are soluble in mercury, but some (such as iron) are not. Amalgams are commonly used in dental fillings.\n\nAn amalgam is also any combination of two or more different things.

Depending upon whether it is metallic mercury or a mercury compound, different rules apply.\nYou can get some ideas at the site below:

Some mercury compounds take the form of crystals.\n\nInorganic mercury compounds take the form of mercury salts and are generally white powder or crystals, with the exception of mercuric sulfide (cinnabar) which is red. Inorganic mercury compounds have been included in products such as fungicides, antiseptics or disinfectants. Some skin lightening and freckle creams, as well as some traditional medicines, can contain mercury compounds.

Just about everything:\n\nFuel, paint, polymers(plastics, film), computers - making those memories and motherboards requires chemistry as well as physics, it's a process called etching. \nMaking drugs, tissue engineering. \n\nI think it's easier to ask what in our life doesn't involve chemistry.

They are made up of a complex double salt:CALCIUM SULPHATE.CALCIUM SILICATE          \nformula:CaSO4.CaSiO2.\nThe teeth is covered by an enamel of a highly inert and non reactive coating that does not react with most of metals and non-metals. But it can be deatched by excessive rubbing of teeth b either brushing or chewing.

d) bond to carbon\n\nThis nonmetal has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly ten million known compounds.

Mercury alloys with several other metals; these alloys are known as amalgams. Dental alloy contains mercury (from 43% to 54%) along with silver, tin, zinc and copper.\n\nhttp://en.wikipedia.org/wiki/Dental_amalgam\n\nSome obscure mercury alloys occur naturally:\nParaschachnerite Ag3Hg2 \nSchachnerite Ag1.1Hg0.9 \nWeishanite (Au, Ag)3Hg2 \nLuanheite Ag3Hg \nKolymite Cu7Hg6 \nEugenite Ag9Hg2 \nBelendorffite Cu7Hg6 \nMoschellandsbergite Ag2Hg3 \n\nhttp://www.galleries.com/minerals/elements/\nhttp://www.galleries.com/minerals/elements/moschell/moschell.htm

Nothing is totally insoluble.\nThe mercury in dental amalgam forms an intermetallic compound with the silver and tin to form a very insoluble inorganic compound. The tiny bits that dissolve are easily excreted by your body. It does not accumulate in your body.\nIt is the organic compounds of mercury (e.g. methyl mercury) as commonly found in fish which can accumulate in your tissues and have the potential to cause damage. It's extremely rare \nto hear of poisoning nowadays - usually industrial incidents.\nTo say that white fillings (composites) are better than amalgams is incorrect. It's like saying apples are better than pears. In which way? Sure, composites look better, but they are also more likely to have post-op pain and failure than amalgams. And when failure occurs in teeth, you usually end up with a bigger problem. All my amalgams are 30+ years old, and will probably outlast me.\nSome people will do anything for $, so ask yourself - why doesn't my dentist just do white fillings all the time if he can charge higher fees? And do you think you'll get better quality in an Eastern Bloc country where you'll have no recourse if things go wrong?\nLater... sorry andyy (below), good lateral thinking but it doesn't work that way. There would be no adhesion between the white filling on top and the amalgam underneath, therefore leads to leakage and decay.\nInlays (fillings made outside of the mouth and then glued in) would be the best sort of white filling. They are very hard-wearing and stable. But very expensive for most people. Most people think of white fillings as directly placed composites.
