Bulk MgB2 superconductor with high critical current density synthesized by self-propagating high-temperature synthesis method

Pure MgB2 bulk samples are successfully synthesized by self-propagating high-temperature synthesis (SHS) method. The experiments show that the best preheating temperature is 250°C, the highest Jc values of the prepared MgB2 reach 1.5×106A/cm2 (10K, 0.5T) and 1.7×106A/cm2 (20K, 0T) and the MgB2 particle sizes range from 2 to 5μm. The advantages of this method are that it is simple, economical and suitable for the manufacture of bulk MgB2 materials on industrial scale.
