Va. Tyumentsev et al., Effect of vacuum heat treatment on the graphitization behavior of sulfur-containing carbon, INORG MATER, 35(7), 1999, pp. 688-694
The effects of heat treatment in vacuum and at atmospheric pressure on the
structural transformation of carbon materials containing similar or equal t
o 0.5 to similar or equal to 2.5 wt% sulfur are studied.
