May 13, 2018 The use of pure gold in dentistry is rare; typically, it’s mixed with other metals to form what’s called gold alloy. However, pure gold is occasionally used for very small cavities in the mouth. Gold fillings also last the longest of all the filling materials available. As a result of this and other factors, gold tends to be one of the more ...

Nov 29, 2017 Gold is a popular, though expensive material for plating, taping and protecting equipment. Despite its price, designers use gold because of its extremely beneficial properties in the vacuum of space. Gold absorbs light well, reflects radiation away from the satellite, does not react to atomic oxygen and conducts heat and electricity extremely well.
