Abstract:
一种银掺杂铁基超导体的制备方法,属于铁基超导材料技术领域。包括以下步骤:在氩气保护下,将稀土和As粉末封装在石英管内热处理制备LnAs粉;在氩气保护手套箱内,将LnAs和Fe粉、Fe2O3粉、FeF3粉按摩尔比3∶(1+x)∶(1-x)∶(1.1~1.5)x配比(0<x<0.6),加入银单质,研磨压制成片状;在高真空下退火:0到600℃升温速率1~5℃/min;600℃到900℃升温速率1~3℃/min;900℃保温5~15小时,900℃到(1100℃~1200℃)升温速率1~3℃/min;1100℃~1200℃保温20~30小时;炉冷至室温。通过加入银单质,提高铁基超导体的电磁性能和实用性。
