Abstract	The formation of oxide superconducting phase fabrication of superconducting wire materials and fabrication of precise superconducting material were studied for developing superconductor application technique. The ZrO_2 addition reduced the particle size BaZrO_3 trapped in the matrix after the sintering growth. The added ZrO_2 was converted to fine particles of BaZrO_3 which is the conventional sintering temperature for YBaCuO, Y_2Ba_1Cu_1O_5 and CuO are formed as by products of the reaction between ZrO_2 and YBaCuO phase. The formation of highly BaZrO_3 particle appears to be responsible for the refinement of BaZrO_3 phase after the citric acid sintering process.
