Ceramic Metal Composites

CERMETs are composites of ceramics combined with metals. Most ceramics are oxides of aluminum, magnesium, and beryllium. They are typically strong but brittle and offer both thermal and electrical insulating attributes. Metals on the other hand are more malleable and are usually good thermal and electrical conductors. Combinations of these features offer innovative applications. Rapid […]

3D Printing Graphene Aerogels

Aerogel, aka “frozen smoke” is a light, porous, nearly translucent, matrix of silica, made by removing the liquid part of a gel. Aerogels can also be made from metals and from carbon. Graphene versions of aerogel offer intriguing combinations of strength and electrical conductivity. Lawrence Livermore Laboratory is working on a process that uses 3D […]
