ABSTRACT:
A uniform reticulated intrastructure (56) is placed in a container (58) and surrounded by beryllium powder (72). After closing the container (58) and applying heat and pressure, a hardened form is taken out of the container. The intrastructure (56) is then removed leaving a lightweight solid beryllium body (72) suitable for use as a mirror (52). Means (62, 66) are provided to control the spacing of the intrastructure elements during the forming process.
