Notes:
The effects of BaF2 on thermal behavior and microstructure of melt-processed YBCOsuperconductors have been investigated. The differential thermal analysis (DTA) results indicatedthat the peritectic decomposition temperature of YBCO precursor powder was lowered when BaF2was added (from 1020[removed info] to 976[removed info]). The peritectic decomposition temperature was lowest at thecontent 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 [removed info][removed info][removed info] of BaF2 [removed info][removed info][removed info][removed info][removed info][removed info][removed info]microstructure[removed info][removed info]
