An investigation of sintering kinetics of boron and boron carbide is presented. The in6uence of the powder size distribution on the temperature dependence of sintering, on reaching a high 5nal density, and on gaining a homogeneous grain size has been shown. The results on the -rhombohedral usage in
The vibrations of boron carbide B 13 C 2 have been studied by the valence force model. The 1560-cm Ψ1 band is ascribed to the antisymetric stretching of the linear chain, and thereby it is IR active only. Large angle-bending forces of the carbon atoms are estimated to agree with the experiment. This
