Abstract
We present first principles calculations for the structural properties of α-berlinite (AlPO4) as a function of pressure. The calculations were performed within the local density approximation using ab initio pseudopotentials and a plane-wave basis. We determined the lattice parameters, cohesive energy, and bulk modulus by minimizing the enthalpy of the solid with respect to lattice parameters. We find good agreement, within ∼2–3% of the experimentally observed values, for the structural properties as a function of pressure.
