| 摘 要： | 最近发现的水合钴氧化物超导体引起了超导领域的强烈兴趣．由于该超导体非常不稳定，因此有关该超导体的合成和表征是个重要的基本课题．本文报道几种典型的合成方法，并对所得到的超导体进行表征．我们将着重介绍利用歧化反应来制备含有很低的钠离子浓度和很高的水合氢离子浓度的钴氧化物超导体的新方法．

| Abstract: | Recent discovery of the first cobalt oxide superconductor has received much attention. The new superconductor shows extreme chemical instability under ambient environment, therefore, the synthesis and characterization of the superconductor becomes an important issue. We present the characterizations as well as some typical synthetic method in this paper. A superconductor with very low content of sodium and very high content of hydronium through a disproportionation reaction route is reported. |
