摘要：

AlSb has been studied in a diamond anvil cell by energy dispersive X-ray diffraction with a synchrotron source to 50 GPa. The measured equilibrium transformation pressure and change in volume for the first order phase transformation between the initial zinc blende and high pressure beta-Sn phases is P-e = 5.3 +/- 2 GPa and Delta V = 15 +/- 1% as a result of loading and unloading transition studies. Equations of state were obtained for both phases. A transformation from the beta-sn to an unknown structure started at 43 GPa.
