ABSTRACT:
A method for improving the phase purity of a multiphase ceramic high temperature superconductor by selective microwave heating of undesired phases in a multiphase material to cause a phase transformation of the undesired phase to the desired phase. The selective microwave heating may be employed during initial firing and sintering of the ceramic superconductor compound or as a subsequent annealing step. Plane polarized microwave energy may be employed to enhance the two dimensional anisotropy of the compound by similar selective heating.
