In this research, the development of fabrication technique of bulk YBaCuO superconductors for application was studied. In fluence of BaZrO3 addition on magnetization characteristics of thermal pyrolysis textured YBaCuO superconductor was investigated. Fine BaZrO3 particle were dispersed within the textured YBaCuO matrix by means of the thermal pyrolysis processing. Magnetic levitation force for YBaCuO superconductors were obtained using Nd-B-Fe permanent magnet, at 77 K and at the magnetic field from 0 to 5.3 K gauss. In the unadded superconductor and 5 wt% BaZrO3 addition, anomalous magnetization behavior, which is characterized by the intermediate magnetic field, was observed at 77 K. Critical current density was about few hundreds A/㎠ and the magnetic characteristics increased slightly by addition of BaZrO3 powder. Maximum magnetic force was obtained in the YBaCuO superconducting bulk with 3 wt.% BaZrO3 addition.
