The high pressure behavior of aluminum tungstate [Al{sub 2}(WO{sub 4}){sub 3}] has been investigated up to {approx}18GPa with the help of Raman scattering studies. Our results confirm the recent observations of two reversible phase transitions below 3GPa. In addition, we find that this compound undergoes two more phase transitions at {approx}5.3 and {approx}6GPa before transforming irreversibly to an amorphous phase at {approx}14GPa.
