尽管MgB2超导线材的临界转变温度相对较低,但MgB2没有晶界弱连接,因而具有低的加工成本,相对于BSCCO和YBCO表现出明显的应用优势。
Although the critical transition temperature of MgB2 superconducting wire is relatively low, MgB2 has no weak connection of the grain boundaries and thus has low processing cost, showing obvious application advantages relative to BSCCO and YBCO.
