Siliconated pyrolytic graphite

Part 1 Preparation and some properties
  • Seishi Yajima

Siliconated pyrolytic graphite PG(Si) has been prepared by pyrolysis of a mixture of propane and silicon tetrachloride vapour at 1440 to 2025° C, a total gas pressure of 10 or 50 torr, and a partial pressure of silicon tetrachloride vapour of up to 13 torr. The amounts of silicon in PG(Si) are 0.02 to 4 wt %. The effects of the addition of silicon tetrachloride on the surface characteristics, the microstructure and the density of PG(Si) are examined.
