AB - Ceramic composite materials consisting of a boron carbide (B4C) matrix and titanium diboride (TiB2) secondary phase werein-situ manufactured via chemical reaction of B4C and titanium diboride (TiO2) during hot pressing at a temperature of 1850°C under a pressure of 35 MPa for 60 min in a vacuum atmosphere. The TiO2 addition has a positive effect on bothdensification of B4C-TiB2 ceramic composites and portion of TiB2 secondary phase. When adding 10 to 50 wt.% TiO2 to B4C,sintered densities increased from 92.1 to 99.5% and portion of TiB2 secondary phase increased from 3.9 to 40.2 vol.%. Whenincreasing the TiB2 portion to its maximal value, the fracture toughness of the composite reached the maximal value of 7.51MPa.m1/2. The hardness of B4C-TiB2 composite improved when increasing the portion of TiB2 phase only up to the value of29.7 vol.% when it reached the average value of 29.8 GPa.
