At Which Temperature Ceramic Materials Behave As Superconductors?

At Which Temperature Ceramic Materials Behave As Superconductors? At which temperature ceramic materials behave as superconductors? Super conductor is the material that can conduct electricity with zero resistance. Ceramic material act as super conductors at 150K. Can ceramics be superconductors? Ceramic superconductors can be prepared using an oxalate precursor [3, 4] which can be transformed
