PRODUCTION OF BISMUTH-CONTAINING OXIDE SUPERCONDUCTING MATERIAL

摘要

PURPOSE:To produce a Bi-contg. oxide superconducting material having an increased critical temp. at which transition to superconductivity is attained an improved superconducting characteristics. CONSTITUTION:Powdery starting materials for a Bi-contg. oxide superconducting material are heated in a low oxygen atmosphere under <=0.1 atm partial pressure of oxygen and the heated starting materials are molded and fired to produce a Bi-contg. oxide superconducting material.
