    • A method of preparing a binary, ternary or higher metal oxide material containing copper and as one or more cations Y and/or any lanthanide rare earth element and capable of displaying superconductivity above 77K, comprising preparing said material such that said Y or lanthanide rare earth cation(s) is/are partially substituted by a substituent cation or cations which exhibit chemical valency lower than that of the substituted cation, to an amount of the substituent(s) effective to achieve a rate of oxygen diffusion or rate of oxygen exchange within an oxygen-containing atmosphere sufficient to enable oxygen exchange or oxygen diffusion into or out of said material to achieve the oxygen stoichiometry in said material whereby the material exhibits said superconductivity above 77K in a reduced time relative to that required to produce the equivalent unsubstituted material of the same porosity exhibiting superconductivity at the same temperature by otherwise the same method, including carrying out said oxygen diffusion or exchange in said reduced time.
    • 一种制备二元,三元或更高金属氧化物材料的方法,其包含铜和一种或多种阳离子Y和/或任何镧系元素稀土元素并且能够显示高于77K的超导性,包括制备所述材料,使得所述Y或镧系稀土 阳离子部分被取代阳离子部分或化学价低于取代阳离子的阳离子部分地取代成有效地达到氧扩散速率或氧气交换速率的取代基的量 足以使氧气交换或氧气扩散进入或流出所述材料的含氧气体,以实现所述材料中的氧化学计量,由此该材料相对于产生等效的未取代材料所需的时间在缩短的时间内显示超过77K的超导性 相同的孔隙率在相同的温度下表现出超导性,否则以相同的方法,包括汽车 在所述减少的时间内消除所述氧气扩散或交换。
