Abstract

The interactions of partially melted Er-Ba-Cu-O superconductors with various substrates including MgO, TiO₂, SiC and PSZ were studied with the objective of finding an adequate buffer layer for a nickel-HTSC composite. Bulk ErBa₂Cu₃O_x pellets were melt-textured on the substrates and the superconductive properties of the composites were assessed by AC susceptibility. In the present paper, microstructure of the textured superconductors and the interfaces are described. Contamination of 123 grains by the various materials and the composition of the reaction products are presented.
