The Effect of the Pressure for the Formation of YBa_2Cu_3O_(7-d) Bulk Ceramics with Domestic Microwave Oven

摘要

We fabricated YBa_2Cu_3O_(7-d) bulk ceramics with a domestic microwave oven and investigated the effect of pressure at the press procedure. If the pressure was not high enough, the ratio of BaCuO_2 phase became large, estimated from x-ray diffraction (XRD) measurements. We found that the pressure should be 700 kgf/cm2 at least in order to suppress the BaCuO_2 phase.
