摘要:
一种MgB
摘要(英):
The present invention relates to a novel MgB2 superconductivity material with high critical current density and its preparation method. It is characterized by that in the MgB2 superconductivity material, one method element Me selected from Ti, Zr, Mo, Nb, W or Hf is doped, and the mole ratio of its composition is Mg:Me:B=(0.8-0.9):(0.1-0.2):2. Its preparation method includes the steps of proportioning Mg powder, Me powder and B material component, mixing them uniformly and sintering at normal pressure in argon atmosphere. This invented MgB2 superconductivity material possesses high critical curcent density at above 10K temp., and its performance also is excellent under the magnetic field.
