A mixture or an alloy of mercury with a number of metals or alloys such as sodium as well as with some non-metals is known as amalgam.

Uses:

1. Sodium is highly reactive metal and therefore it is difficult to transport. To lower its reactivity, it is mixed with mercury.

2. Dental amalgam is a mixture of mercury and a silver-tin alloy and is used for fillings in teeth.

Amalgam fillings are often known as “silver fillings.” Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50% of the compound, binds the metals together to provide a strong, durable filling.
