二硼化镁 meaning in English
magnesium diboride
Examples
- It has weak - link free grain boundaries and is a kind of low cost material , . which could be used under 20k ~ 30k . however , mgb2 reveals a poor jc property in high magnetic field . currently in the research of the mgb2 wires and tapes many efforts have been made to improve its grain connection or enhance the jc dependence on the magnetic field using the method of chemical doping
二硼化镁是迄今为止所发现的超导临界转变温度最高的非铜氧化物超导材料,它具有无弱连接、成本低廉、能够在20k 30k应用等优势,但是mgb2在外场下的临界电流特性较差,目前在优化粉末套管法制备mgb2线带材工艺的研究中,通过改善晶间连接和利用化学掺杂提高样品的超导临界电流密度是mgb2成材研究的一个重要方向。
