1. The highest jc of 8 . 64 105a / cm2 at 10k , 0t was obtained in the un - doped mgb2 / fe tape sintered at 800 for 15 minutes by sps . it is worthwhile to note that the jc value was decreased much slowly in this sample with the increase of the testing temperature and magnetic field . for example , the jc was 5 . 97 105a / cm2 at 20k , 0t , and at 20k , 3t the jc value was
   从目前试验结果看,掺杂量为5mol %时线材性能较好,样品的临界电流密度在自场下达到6 105a / cm2 ,并且sic掺杂改进了样品在高场下的jc值,在4t时,掺杂线材样品的临界电流密度大大超过未掺杂样品,这是由于sic的掺入生成了细小均匀的mg2si ,分布在晶粒
2. The x - ray diffraction , scanning electronic microscope and the squid were used to characterize the properties of the mgb2 core in mgb2 / fe tapes and wires . the effect of the proportion of mg , b and sic as well as the sintering parameters on the phase formation , microstructure and the critical current densities of mgb2 / fe tapes and wires was discussed in details . the results showed that the high purity of mgb2 core could be synthesized by both the traditional vacuum sintering and the sparking plasma sintering and the vacuum sintering environment restrained the oxidation of mg effectively
   相对于传统真空烧结, sps烧结方式成相速度快、样品晶粒细小均匀、 mgb2超导芯致密性好、晶间连接优良,因而sps烧结样品的临界电流密度明显高于传统真空烧结样品,其中未掺杂的带材样品经过sps800 , 15分钟烧结后,自场下的临界电流密度jc值在10k时达到8 . 64 105a / cm2 ,而且随着测量温度和外加磁场的增加, sps烧结样品的临界电流密度下降率比传统真空烧结样品缓慢,在20k ,自场时为5 . 97 105a / cm2 , 20k , 3t时,临界电流密度值仍大于104a / cm2 。
