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.
