Which Materials Are Used As Superconductors? Superconductors and superconducting materials are metals, ceramics, organic materials, or heavily doped semiconductors that conduct electricity without resistance. Superconducting materials can transport electrons with no resistance, and hence release no heat, sound, or other energy forms. How is a superconductor made? When lead, mercury and certain compounds are cooled
