This paper presents the results of experiments and analyses to quantify the chemical reactivity of plasma-sprayed (PS) Be specimens exposed to steam. Test specimens with densities of 94% theoretical density (TD) and 92% TD were prepared by a low-pressure-plasma-spraying (LPPS) technique. Sample density, porosity and specific surface area were measured using immersion density and gas-adsorption techniques. Microstructural characterization was done using optical and electron microscopy. Hydrogen generation rates were obtained from tests of specimens in steam at temperatures from 350 to 1000°C. Below 700°C, hydrogen generation rates for the 94% TD material were somewhat higher than rates for 100% TD Be, but they were substantially lower than rates for the 92% TD Be and for previously tested PS-Be and porous Be. Reaction rate differences correlated with specific surface area differences for the materials tested.
