Chemistry does not deal in explaining superconductivity.
*In superconducting materials the charecteristics of superconductivity appear when the temperature is lowered below a critical temperature.
*The onset of superconductivity is accompanied by abrupt changes in physical properties which are more related to phase transitions of the material .
These aspects of studies in properties of materials are better related to studies in the fields of Physics , eventhough principles involved in Chemistry & Physics go hand to hand.
