The transport critical current density Jc in the ceramic superconductor YBa2Cu3Ox was improved by an intermediate vibration introduced during the preparation process. A dependence of Jc on the vibrational parameters, frequency and amplitude, was found. The improved Jc was shown to be accompanied by the enhancement in the orientation degree. Furthermore, a theoretical discussion was tried to explain the Jc dependence.
