Abstract: A process for the removal of adsorbed water from the surface of powder materials includes the step of flowing a heated gas over the powder. The temperature of the gas is below the cracking temperature of the water. The gas is inert with the powder. An ultraviolet light is applied to the powder at a wavelength that will pass through the gas, heat the adsorbed water and desorb it, and reflect from the powder. The ultraviolet light has a wavelength between 10-185 nm. Water is removed from the powder with the flowing gas.
