Vanpeteghem, C.B., Ohtani, E. and Kondo, T. (2002). Equation of state of the hydrous phase d-AlOOH at room temperature up to 22.5 GPa. Geophysical Research Letters 29: doi: 10.1029/2001GL014224. issn: 0094-8276.

The equation of state of δAlOOH has been determined at room temperature up to 22.5 GPa by angle-dispersive x-ray diffraction using synchrotron radiation. The isothermal bulk modulus K0T was found to be 252 (¿3) GPa, assuming that its pressure derivative K'0T is 4, by fitting a third order Birch-Murnaghan equation of state. δAlOOH is thus the least compressible hydrous phase known with compressibility comparable to that of corundum and stishovite, confirming that this phase can be stable at the lower mantle conditions.
