Resorcinol--formaldehyde (RF) aerogels satisfy inertial confinement fusion requirements for cell size and density. The cell size is <0.1 ..mu..m for densities ranging from 65 to 100 mg/cm/sup 3/. Uniformity as measured by x-ray radiography appears good, but careful machining of the RF piece is needed to prevent machine marks from interfering with interpretation. The RF aerogel is wettable with liquid hydrogen, and can be machined to 7-..mu..m surface finish. Stability of that surface over time needs to be improved. Radiation stability, methods of gluing and overcoating, and the thermal expansion coefficient still need to be determined.
