X-ray propagation-based holography is a promoting phase-contrast imaging techniques for fast non-destructive observation in a single shot. We have been using X-ray mirror optics to make available a beam with a small focusing diameter and high flux. To enhance resolution, surface roughness must be controllable to the nano-level. We report on the basic study of tungsten silicide, which is useful for reducing surface roughness.
