High Tc superconducting compounds are made by forming a reaction mixture of the oxides of Sr, Cu, Ca and TI, compressing these into a hardened body, and placing the hardened body into a container. The container is then evacuated and sealed. The hardened body is heated under pressure until the oxides of Sr, Ca, Cu, and TI react to form a superconducting compound.
