Refractory Open-Cell Foams:
Carbon, Ceramic, and Metal
Reticulated Vitreous Carbon Foam
With its patented fabrication process, Ultramet manufactures reticulated vitreous carbon (RVC) foam in a broad variety of shapes and pore sizes. RVC foam has 97% open porosity, low pressure drop, and a three-dimensional cellular structure.
Advantages
- Extremely lightweight
- Thermally insulating
- Electrically conductive
- Easily machinable to near-net-shape
- Stable at high temperatures
- Resistant to thermal shock
- Chemically inert
Applications
- Molten metal filtration
- Energy storage devices
- Catalysis
- Biomedical devices
- Furnace fixturing and tooling
- Electric contactors
Ultramet fabricates RVC foam in pore sizes of 10, 20, 30, 45, 65, 80, and 100 ppi. In addition, Ultramet manufactures compressed RVC foam, which provides anisotropic properties.
