The activated sintering processes of boron carbide with 1%~4% carbon as activator were studied. The mean size of boron carbide ultra fine powder was 0.42 μm. The relationships between the density, bending strength and grain size of the sintered compact and the quantity of additives, sintering temperature, sintering time were investigated. It was showed that the density of the sintered compact increased even with the addition of little amount of additive(carbon). The optimum amount of the additive (carbon) is 1%~2%, and the optimum sintering temperature is 2 160~2 200 ℃. The activated sintering kinetics of boron carbide with carbon as activator were also researched, the results showed that the main transport mechanism was grain boundary diffusion. Finally, the constitntion of carbon phase was studied, it was showed that the form of the added carbon after sintering was free carbon besides those dissolved in boron carbide, and no new phase was formed.
