abstract The paper concerns the activated sintering of boron carbide based materials. The work shows the influence of introduced Cr3C2, CrSi2, Cr3Si modifiers on the sintering of commercial boron carbide. A high-temperature graphite dilatometer was used in order to investigate boron carbide sintering with various additives. The shift of the onset and endset sintering temperature of different sample compositions was determined. The influence of chromium compounds on sintering was explained by XRD phase analysis. The phase changes in the sinters vs. increasing volume fraction of the additives were made. The same analyses were made on samples heat-treated close to the onset sintering temperature.
