Synthesis of MgB2 film by electrochemical process

Abstract

In order to synthesize MgB2 films, electrolysis is performed in an electrolyte comprising a fused mixture of B2O3, KCl and MgCl2 in a molar ratio of B2O3:KCl:MgCl2=x:3.5:5. The results of the Meissner effects and X-ray diffraction measurements indicate the formation of MgB2 films on graphite and Si substrates. The superconducting critical temperature depends on both the synthesis temperature of the electrolysis and the amount of B2O3 in the electrolyte.
