Abstract：The pretreatment temperature for the specific surface area analysis of superfine hexanitrostilbene particles was investigated and obtained by thermal analyzer and surface area analyzer by gas absorption. The results of hexanitrostilbene particles weightlessness and specific surface area as well as its pore distribution at the different temperature were compared. It was shown that the pretreatment temperature of 55～65 ℃ was proved feasible for the specific surface area analysis of superfine hexanitrostilbene particles， and the error of the specific surface area value of hexanitrostilbene particles decreased.
