PRODUCTION OF TL-CONTAINING OXIDE SUPERCONDUCTOR

PURPOSE:To obtain a high critical temp. by firing a starting material blend contg. Tl, Ba, Sr, Ca, etc., in a prescribed atomic ratio in an oxygen-contg. atmosphere. CONSTITUTION:Starting materials are blended so that Tl, AE (Ba or Sr), Ca, RE (rare earth element) and Cu are contained in 2:2:(1-x)(n...
