【 摘 要 】

The hot-pressing production technique of high-density ceramics on polydisperse boron carbide base with an average particle size of 2.1 μm was studied. In some cases, a highly dispersed powder of chromium carbide was used as a sintering additive. Features of the structure were analyzed. The presence of pores between the grains was identified. Morphology of grains characteristic of highly dispersed boron carbide is observed.
