Abstract
Superconductivity and structure of YBCO with added WO3 have been inves tigated. The result indicates that the addition of up to 5% WO3 does n ot destroy the superconducting properties of YBCO. It is found that th e samples with the WO3 addition directly quenched from 900-degrees-C i n an oxygen atmosphere have a transition temperature of 88 K. The tetr agonal-to-orthorhombic transformation takes place within a short time in the YBCO-WO3 samples. Extra peaks can be observed in the x-ray diff raction pattern, indicating that there is a second phase in the sample s.
