Abstract: The inflammable carbon was prepared from poplar carbon which is carbonized from poplar chip, adhesive and ignition agent. Influences of adhesives, the ration of adhesive/carbon, type and content of ignition agent molding pressure and molding time were investigated. The optimum conditions were the adhesives A/poplar carbon ration of 0.6, potassium nitrate ration 5%, molding pressure 25 MPa, molding time 2 minute. The inflammable carbon was non-toxicity, smokeless, flavorless and quickly burning in 5 s, and have 8.60 N/mm2 of factor of against crushing, 6.33% of remains content, 11.20 min/g of combustion last time and 35 762.76 J/g of heat release. This study can provide basis for forming adhesive in development of powder fuels.
