Keywords:
magnesium diboride,, self-propagating high temperature synthesis,, high temperature centrifuge,, superconductivityAbstract
The superconducting material based on magnesium diboride by self-propagating high temperature synthesis (SHS) under the effects of centrifugal force is considered a possibility of an investigation. SH-synthesis of magnesium diboride samples from magnesium and boron powders were performed in a high centrifuge. The spin speed of centrifuge was varied from 2000 to 2500 rpm. The optimum conditions of synthesis of superconducting magnesium diboride were selected. The critical transition temperature (Tc) parameters were determined by using magnetometric measurements on installing Quantum Design PPMS EverCool-II. It was found that the critical transition temperature of the samples is in the range 37.5-38K. The critical current density (Jc) of sample in its own magnetic field was calculated, which is equally 0.8-1* 108A/cm2. It is found that the value of the centrifuge shaft speed significantly influences on the synthesis and superconducting characteristics of magnesium diboride.
