Overview

Randomized trial investigates properties of graphite whiskers synthesized under high pressure conditions, suggesting significant material potential.

Key Points

  • The aim is to investigate the growth, structure, and properties of graphite whiskers produced in a controlled environment.
  • Graphite whiskers were grown in a dc arc at 3900°K under 92 atmospheres of argon pressure.
  • The whiskers were embedded in a solid matrix formed by diffusion of carbon vapor.
  • Characterization included measuring diameter, length, tensile strength, and resistivity.
  • Diameters of whiskers ranged from a fraction of a micron to over five microns with lengths up to 3 cm.
  • Tensile strengths reached up to 2000 kg-mm−2 and Young's modulus exceeded 7×1012 dyne-cm−2.
  • Room-temperature resistivity was approximately 65 μohm-cm, close to single crystal values.
