Abstract

Effects of sintering time and temperature on the superconductivity and microstructure of bulk MgB₂ were investigated. AC magnetic susceptibility measurements show that T_C increases with sintering time. The magnitude of change in T_C is larger when varying the sintering time as opposed to varying the sintering temperature. SEM showed that the increasing size of MgB₂ grains resulted from partial melting attained through sintering at a longer period of time, and that there is no significant change on the grain sizes of MgB₂ with increasing sintering temperature.
