The article is devoted to the impact of carbon additives on densification and mechanical properties of ZrC/C heteromodulus composites. In case of addition of small amount of carbon to ZrC residual porosity decreases, whereas higher carbon content leads to more than 3vol.% increase in residual porosity. Moreover, increase in carbon content in ZrC/C composites boosts toughness of sintered materials. For example, IC =4.3 MPa×m1/2 for ZrC and IC =7 MPa×m1/2. for 3 vol.% C. For 15 vol.% of C, toughness is the lowest and equals 5.3 MPa×m1/2. The extrapolation of the dependence of toughness on the non-porous state of materials is IC0 =13.2 MPa×m1/2.
