摘要： A carbonaceous heat source for a smoking article is provided. The heat source is designed to maximize heat transfer to a flavor bed in the smoking article. The heat source undergoes substantially complete combustion leaving minimal residual ash, has a relatively low degree of thermal conductivity and ignites under normal lighting conditions for a conventional cigarette.
