Abstract
The effects of BaF2 on thermal behavior and microstructure of melt-processed YBCO
superconductors have been investigated. The differential thermal analysis (DTA) results indicated
that the peritectic decomposition temperature of YBCO precursor powder was lowered when BaF2
was added (from 1020 to 976). The peritectic decomposition temperature was lowest at the
content of 5 wt.% BaF2, and the variation of melting temperature was not significant above 5 wt.%
BaF2. The microstructures of the doped samples have been observed by scanning electron microscopy
(SEM). The results showed that the
of BaF2
microstructure .
