Title: Method for preparing hydride configurations and reactive metal surfaces

Abstract

A method for preparing highly hydrogen-reactive surfaces on metals which normally require substantial heating, high pressures, or an extended induction period, which involves pretreatment of the surfaces with either a non-oxidizing acid or hydrogen gas to form a hydrogen-bearing coating on the surfaces, and subsequently heating the coated metal in the absence of moisture and oxygen for a period sufficient to decompose the coating and cooling the metal to room temperature. Surfaces so treated will react almost instantaneously with hydrogen gas at room temperature and low pressure. The method is particularly applicable to uranium, thorium, and lanthanide metals.
