We have succeeded in synthesizing samples of new filled skutterudite compound BaOs4P12 using the high-pressure synthesis technique. The physical properties of the compound are reported for the first time. The electrical resistivity decreases with decreasing temperature, and drop sharply around 1.8K. This indicates that BaOs4P12 is a new superconductor. Before the high-pressure synthesis, using synchrotron radiation x-ray, we tried to observe synthesizing processes of BaOs4P12 in-situ at high temperature and high pressure to obtain the optimum condition for synthesis.
