Abstract

A new method to prepare high purifying trifluoroacetate (TFA) coating solution according to the mechanism of neutralization reaction between the hydroxid of Y, Ba, Cu and TFA is reported. High-quality YBa2Cu 3O7-x (YBCO) thick films on texture Ni tapes with NiO buffer layer have been successfully fabricated by the coating solution. The effect of heat treatment process including firing process and atmosphere on the microstructure and properties of YBCO films were studied by X-ray diffraction and scanning electrical microscope. The results show that coating solution can decrease the microcracks in film by appropriate heat treatment process and the grain size of YBCO approach to nanometer level.
