DEFINITION

Classification: 148/96

Superconductive metal or alloy (i.e., superconductive Tc at or below 30 deg. K):

(under subclass 95) Process wherein a metal or an alloy of metal that develops zero resistance to electrical current flowing therethrough at or below 30 deg. Kelvin is the metal being treated.
