| Abstract |
For the fabrication of YBa_2Cu_3O_x thick film, a substrate of Y_2BaCuO_5 was fabricated by adding CeO_2 into Y_2BaCuO_5 and two types of doping materials added with binder material were prepared. Each doping material was patterned on Y_2BaCuO_5substrate by the screen printing method and then was annealed at the temperature with a few step. It could be observed by X-ray diffraction patterns and SEM photographs that through the diffusion process of the Y_2BaCuO_5 and each doping material, the YBa_2Cu_3O_x phase was formed. And with n additive of CeO_2 the thickness of formed YBa_2Cu_3O_xdecreased. From the experiment of current limiting on thick film, the sample with thiner thickness of YBa_2Cu_3O_x showed the more effective characteristics of current limiting. |
