These cases are illustrated by yttrium barium copper oxide (YBCO; chemical formula YBa₂Cu₃O₇), shown in Figure 2D. YBCO is a superconducting ceramic; that is, it loses all resistance to electric current at extremely low temperatures. Its structure consists of three cubes, with yttrium or barium at the centre, copper at…

Within a year an yttrium barium copper oxide ceramic, YBa₂Cu₃O₇, had been discovered to have a T_c higher than 77 K, the boiling point of nitrogen (−195.8° C, or −320.4° F). This finding raised the possibility of practical superconductors being cooled by liquid nitrogen—as opposed to conventional superconducting materials,…
