Research and Development on Advanced Graphite Materials. Supplement to Volume XIII. Development of a Fine-Grain Isotropic Graphite for Structural and Substrate Applications

摘要

The characterization of grade RVC graphite and the process and blend variations which were studied in the fabrication of substrate-type graphite are described. Present trials show that a forming pressure of 900 lbs./sq. in., instead of the 1000 lbs. /sq. in. as used previously, would increase the yield of grade RVC and not significantly change the properties of the material. Furthermore, these trials show that various other blends will also produce a substrate graphite suitable for silicon carbide coating. (Author)
