Why Mercury is Used in Thermometers (and Modern Alternatives)
While modern thermometers are usually filled with dyed alcohol, mercury is a better liquid to use. Well, as long as you don’t count mercury’s health hazards. Nowadays, mercury thermometers are...
Refractory metals are the metallic elements with the highest melting point, high hardness, and high density. Conservative definitions of “refractory” refer to 5 industrially useful metals with a...
What Are Superalloys? (Applications, History, and Metallurgy)
Superalloys are metal alloys that can operate at a high fraction of their melting point. Superalloys must have high strength, high melting points, resistance to corrosion or oxidation, and creep...
What Are Shape Memory Alloys? (Metallurgy, How They Work, and Applications)
Shape Memory Alloys (SMAs) are an intermetallic alloy that can be deformed but will return to their original shape when heated. SMAs have a Shape Memory Effect (SME) and pseudoelastic effect, which...
15 lowest melting point metals: Mercury, Francium, Cesium, Gallium, Rubidium, Potassium, Sodium, Indium, Lithium, Tin, Polonium, Bismuth, Thallium, Cadmium, and Lead.
Metals conduct electricity because they have “free electrons.” Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom. This allows...
