Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    The specific electrical resistance of certain carbon composition materials decreases with increasing temperature.

  2. 2.

    Flat heaters fabricated from a carbon/carbon-type material possess anisotropy of electrical conductivity.

  3. 3.

    Current conductors and heaters formed from a carbon/carbon-type material are suitable for service under a moderate vacuum (0.133–133 Pa).
