英文摘要	BaWO4-II has been synthesized at 5 GPa and 610 degrees C. Its high pressure behavior was studied by in situ synchrotron X-ray diffraction measurements at room temperature up to 17 GPa. BaWO4-II retains its monoclinic structure. Bulk and axial moduli determined by fitting a third-order Birch-Murnaghan equation of state to lattice parameters are: K-0 = 86.2 +/- 1.9 GPa, K-0(a) = 56.0 +/- 0.9 GPa, K-0(b) = 85.3 +/- 2.4 GPa, and K-0(c) = 146.1 +/- 3.2 GPa with a fixed K' = 4. Analysis of axial compressible modulus shows that the a-axis is 2.61 times more compressible than the c-axis and 1.71 times more compressible than the b-axis. The beta angle decreases smoothly between room pressure and 17 GPa from 93.78 degrees to 90.90 degrees.
