What is the difference between alloy and amalgam give two examples of each?

Hi friend , Alloy- A metal made by combining 2 or more metallic elements especially to give greater strength or resistance to corrosion. Amalgam-An alloy of mercury with other metals. Example -a mixture of mercury and silver is used to make fillings.

Is amalgam an alloy?

Amalgam, alloy of mercury and one or more other metals. Amalgams are crystalline in structure, except for those with a high mercury content, which are liquid. ... In dentistry, an amalgam of silver and tin, with minor amounts of copper and zinc, is used to fill teeth.

What is the difference between alloy and ore?

An alloy is a homogeneous mixture of elements; at least one of the elements must be a metal. An ore is a naturally occuring mixture (usually heterogenous) that contains a particular metal (or a compound of that metal) in amounts that make extraction of the metal economically worthwhile.

What is the difference between alloy and composite?

An Alloy is a mixture of one or more metals with other elements. Composites are also a mixture of two or more elements, but it does not contain metals. An alloy can either be a homogeneous or a heterogeneous mixture. A composite is always a heterogeneous mixture.

What is amalgam give an example?

The definition of an amalgam is a mixture of metals and mercury, which can be man-made or can be naturally occurring. An example of an amalgam is a mixture of silver and mercury which is used as a dental filling.

What does Alloy mean?

Alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel.

What happens if mercury touches gold?

Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold it will immediately break the lattice bonds of the precious metal and form an alloy in a process known as amalgamation.

Can mercury dissolve gold?

Gold dissolves in mercury similar to the way salt dissolves in water. Miners submerged their ore in mercury, which would take on the gold but not the other impurities.

What is alloy of mercury called?

An amalgam is an alloy of mercury with one or more other metals. Most dental amalgams are called silver amalgams since silver is the principal constituent that reacts with mercury.

What are ores Class 5?

Ores are those minerals from which metal are extracted conveniently and profitably. There are mainly four types of ores such as Oxides; Carbonate Ores; Sulphide; Halides Ores. Reduction with the help of CO and Coke in blast furnace, chemical reduction with CO, Calcination followed by reduction with CO.

Why all ores are minerals?

Ores are defined as the minerals that contain higher concentrations of certain elements which is most of the time metal. All ores are minerals, and metals can be extracted commercially. But all minerals are not ores because some of the minerals have unwanted substances. Was this answer helpful?

What are the most common metal ores?

The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides.
