Uses for Mercury
A. Mercury is found and used in thermometers. Mercury is used in this application as it is a common metal that is liquid over ordinary temperatures. It has a melting point of -39C and a boiling point of 357C. It also has a uniform volumetric expansion making it ideal for thermometers.

B. Mercury is found and used in dental fillings. Mercury can readily form alloys (which is a mixture of two or more elements) with other metals. Alloys containing mercury are called amalgams. Dental amalgam is a mixture of mercury, and an alloy of silver, tin and copper. Mercury makes up about 40-50 percent of the compound. Mercury is used to bind the metals together and to provide a strong, hard durable filling. After years of research, mercury has been found to be the only element that will bind these metals together in such a way that can be easily manipulated into a tooth cavity.

C. Mercury was used in the manufacturing of felt-hats, but this is ...
