1. A relatively rare yellow, brown, or black mineral, CaTiO3, sometimes containing rare-earth elements such as lanthanum.
2. Any of various oxides having a crystal structure similar to that of this mineral and that can be found in many superconducting ceramic materials and in electrodes in fuel cells.
