A method for increasing the pore volume of alumina powder produced by spray drying alumina slurries by heating the slurry to a temperature near the boiling point of water and a pressure up to the critical point of water then introducing the slurry to a spray drying chamber through a small orifice, thereby creating a backpressure in excess of slurry vapor pressure and up to the critical point of water.
