Chapter 5. Carbon Graphite - ScienceDirect

Jan 01, 1992· Some typical seal designs in which carbon graphite is used are shown in Fig. 5.1. Nose pieces in face seals, rings in turbine seals, vanes in positive displacement pumps and rings for dry gas piston compressors use carbon graphite as a basic material. Carbon graphite is an ideal material for these purposes because of several properties.

Materials for use in vacuum - Wikipedia

Porcelain and alumina ceramics, when fully vitrified and therefore non-porous, are excellent insulators usable up to 1500 °C. Some ceramics can be machined. Ceramics can be joined with metals. Macor is a machinable ceramic that is an excellent alternative to alumina, as the firing process of alumina can change the dimensions and tolerances.

Silicon Carbide Whiskers High Quality Less Price Fast

Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength gives this material exceptional thermal shock resistant qualities.
