The property of certain materials, including certain metals, alloys, and ceramics, to superconduct at temperatures ranging from a fraction of a kelvin to about one hundred kelvin.
su′per·con·duc′tive (-kən-dŭk′tĭv) adj.
(General Physics) physics the property of certain substances that have no electrical resistance. In metals it occurs at very low temperatures, but higher temperature superconductivity occurs in some ceramic materials

the disappearance of electrical resistance in certain metals at temperatures near absolute zero and in new classes of ceramic oxides at temperatures well above this.
su`per•con•duc′tive, su`per•con•duct′ing, adj.
The increase in electrical conductivity and decrease in resistance, in certain substances, at very low temperatures.
