AntimonyImpregnated Carbon Graphite Carbon/Graphite and Graphite Materials are inherently porous after the material processing. It is common to impregnate these materials with a Resin or Metal to: Increase the Strength, Increase the Thermal Conductivity, Reduce the Resistivity, Reduce the Porosity, and/or Impart Impermeability. These benefits can lead to secondary benefits such as the ...
