The chemical preparation of ceramic superconductor YBa2 Cu4 O3 (124)power by coprecitation and the studies of its phase transformation
碩士 === 中國文化大學 === 應用化學研究所 === 80 === YBaCuO(124) 超導粉末,對於氧的熱穩定性優於YBaCuO-(123)者, 又化學共沉法製備超導粉末是目前最為人們所樂於接受之超導粉末製程方法中的一 種。本文研究係以化學共沉法製備〝124〞超導粉末,並探討以水溶液、均質溶 液及酒精溶液之草酸沉澱劑,對於共沉粉末顆粒大小及均勻度的影響。加鈉鹽的Y( BaNa)Cu 氧化共沉...
