Abstract

YBa₂Cu₃O_6.5 (YBCO123) was synthesized, subjected to pre-melt process and its microstructures characterized via SEM. The microstructural evolution was observed by pre-melting YBCO123 at the melting temperature onset 1020°C and cooling it down with crystallization cooling rates (CR) 100, 50, 33.3, 20, 10, 5 and 2°C/hr. Microstructural development from a brittle fissured faceted phase with no defined grain boundary and densified melted features to column-like grains and biphasic grains with hexagonal grain boundaries were observed as the CR was varied from fastest to slowest CR.
