Everything about Refraction Metallurgy totally explained
In
metallurgy,
refraction is a property of
metals that indicates their ability to withstand
heat. Metals with a high degree of refraction are referred to as
refractory. These metals derive their high melting points from their strong
intermolecular forces. Large quantities of energy are required to overcome intermolecular forces.
Some
refractory metals include
molybdenum,
niobium,
tungsten, and
tantalum. These materials are also noted for their high
elastic modulus and
hardness.
Binary compounds such as
tungsten carbide or
boron nitride can be even more refractory than metals.
Hafnium carbide is the most refractory binary compound known, with a melting point of 3890 degrees C.
