Abstrakt: The sintering ability and mechanical characteristics of the materials obtained by sintering in the ZrB2–SiC–MoSi2 system are investigated. The density, linear coefficient of thermal expansion 4.9–6.1 × 10–6 K–1, ultimate strength in the bending of ceramic specimens (σmax = 460 MPa), and elastic modulus (up to 360 MPa) are determined; and the microstructure is investigated. The phase composition of some ceramics, in addition to the initial components, contains new phases: MoB, ZrC, and Mo4.8Si3C0.6. [ABSTRACT FROM AUTHOR]
