Abstract

The fundamental aspects of synthesis of expandable residual graphite hydrosulfate with the use of an oxidizing system CrO3-H2SO4 at ultralow consumption of the reagents and their separate introduction into the reaction mass were studied. The dependence of the expansion ratio of the samples obtained on the content of intercalant and expansion temperature was analyzed.
