다국어 초록 (Multilingual Abstract)

Y₁_(x)Ca_(x)Ba₂Cu₃O_(7-8) powder was synthesized by a coprecipitation method. This process is very easy to control the chemistry of the cation's solutions and coprecipitation with oxalic acid. Starting materials Of nitrates such Y(NO₃)₂ · 6H₂0, Ca(NO₃)₂ · 4H₂0, Ba(NO₃)₂and Cu(NO₃)₂ · xH₂O were dissolved into distilled water. Each solution was mixed and pH-controlled with oxalic acid The best condition of coprecipitation was pH 1.3 at room temperature. The yield of precursor was up to 92%. After calcining at 850℃ in air, 123 single phase was obtained. The size of 123 phase powder was about 90nm.
