Ultrafine MgO with uniform shape and particle size was prepared by spraying a solution of magnesium nitrate into an inductively coupled plasma (ICP) of Ar. The formation of the uniform particles seems to result from the complete decomposition of the nitrate to its component atoms in the ICP flame, followed by the precipitation of the oxide occurring just outside the flame.
