Abstract

Abstract SmBa 2 Cu 3 O 7− y (Sm123) was made by a liquid infiltration technique using isothermal peritectic reaction below the peritectic temperature ( T p =1060°C) of SmBaCuO. By heating and isothermal holding, the coupled Ba 3 Cu 5 O 8 /Sm 2 BaCuO 5 (Sm211) powder compacts in the temperature range of 900°C–1050°C in air, the Ba 3 Cu 5 O 8 powder melts and is then infiltrated into the Sm211 compacted powder. The infiltrated liquid phase reacts with the Sm211 phase to form a textured Sm123 structure. The microstructure and the superconducting properties of the samples are reported.
