The heat of formation of boron carbide

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1968
The standard heat of combustion in fluorine of a boron carbide sample having the composition B4.222C was determined from the heats of combustion of polytetrarluoroethylene and of boron carbide-polytetrafluoroethylene mixtures. The energy of the combustion reaction was measured in an isothermal-jacket bomb calorimeter.
