Abstract

The purpose of this research aims to study the physical properties of the Y123 and Y235 superconductor doped fluorine by solid state reaction. The conventional process with the calcination temperature at 810 degrees C and the sintering temperature at 925 degrees C were done. The samples obtained with optimal doping had the highest critical temperature at 95 K and 93 K for Y123 and Y235, respectively. There was no effect of doping on lattice parameters but the anisotropy parameter of Y235 was dependent on fluorine doping. The iodometric titration method was done that the pure Y123 and Y235 were shown the highest of Cu3+/Cu2+ ratio and deficiency parameter. We also found the highest amount of Cu3+/Cu2+ ratio at the optimal fluorine doping.
