✦ Synopsis

The lattice parameters of Al 3 BC 3 have been measured at room temperature up to 7.5 GPa using X-ray powder di4raction with synchrotron radiation. From the obtained pressure+volume relation for Al 3 BC 3 , the isothermal bulk modulus of B 0 ‫؍‬ 153 ؎ 6 GPa and its pressure derivative of dB 0 / dp ‫؍‬ 19 ؎ 4 have been calculated by 5tting a Birch+Murnaghan equation of state. Al 3 BC 3 undergoes no structural transformations up to 1800 K over the 2.5 to 5.3-GPa pressure range.
