In this paper, we will report the superconductivity of Ba1−xKxBiO3 system for various concentrations. A phase diagram around the composition x=0.4 will be studied systematically. It is found that the transition temperature Tc of the sample with x=0.5 is as high as 24K. DC magnetic susceptibility for this x=0.5 sample will be measured to study Hc1 and Hc2. From experiments, an extremely low Hc1 (T) curve is observed, whereas Hc2 (T) curve is relatively high.
