B4C/SiC composites containing different amounts of SiC were been produced by reactive hot pressing of B4C, SiO2 and C powder mixtures using two different processing conditions. B4C, SiO2 and C powder mixtures were prepared by attritor milling in ethanol at 600 rpm for 2 hours. One set of samples was hot pressed at 2200°C under 100 MPa for 1 hour in an argon atmosphere. The second set was hot pressed at 2150°C and 2200°C under 100 MPa pressure in a vacuum. After processing, the phase transformations occurring in the samples were measured by an X-ray diffractometer. The variations in density, hardness and microstructure of the samples versus temperature and sintering atmosphere were investigated.
