materials are the one which holds back its strength at high temperatures.
They are the non-metallic materials bearing those physical and chemical
properties which made them relevant for structures and they are
exhibited to environments above 1000 °F (800K, 500 °C).
These materials are employed in the linings for kilns, furnaces,
reactors and incinerators. Refractory materials are also employed
to create crucibles. Refractory
materials should be physically and chemically constant
at elevated temperatures. They continue resistant to thermal shock
depending on the operating environment.Refractory
materials have particular arrays of thermal conductivity
and constant thermal expansion.
Major materials used for the making up of Refractories include oxides of aluminium, magnesium and silicon. Oxide of calcium
and fireclays are also employed for refractory manufacturing.
Refractories are selected as per the circumstances they are going
to face. Certain applications need exceptional refractory materials.
Zirconia is employed when the materials must resist very high
temperatures. Carbon and silicon carbon are the two refractory
materials employed in hard temperature conditions. But these materials
cannot be employed in touch of oxygen because they will oxidate
