| Abstract: | Pure MgB$_{2}$ bulk samples are successfully synthesized by self-propagating
high-temperature synthesis (SHS) method. The experiments show that the best
preheating temperature is 250℃, 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 5\mum. The advantages of this method are that it is simple, economical and
suitable for the manufacture of bulk MgB2 materials on industrial scale. |
