Zusammenfassung:MgB2 becomes superconducting just below 40 K. Superconducting transition with the onset temperature of 39K was confirmed by both magnetic and scanning electronic microscopy measurements. Magnetization versus field (M-H) curve shows the behavior of a typical Type II superconductor. The bulk sample shows good connection between grains. SEM studies of bulk samples of MgB2 revealed details of the grain boundary structure. Also, the powder X-ray diffraction pattern of the MgB2 powder is presented.
