DEFINITION

Classification: 505/919

Reactive formation of superconducting intermetallic compound:

(under subclass 918) Subject matter wherein the heat treating creates a superconducting layer or portion thereof by means of a chemical reaction involving two or more metallic constituents, at least one of which is generally supplied by diffusion.
