With the view to improve the densification behaviour and mechanical properties of ZrB2-SiC ceramics, three synthesis routes were investigated for the production of ZrB2, prior to the fabrication of ZrB2-20 vol. % SiC via spark plasma sintering (SPS).

Starting from ZrO2 and boron (molar ratio: 1:4), four ZrB2 powders were synthesized by borothermal reduction method, three of which were designed to introduce minor modifications by combining solid solution with Ti and/or water-washing. The sinterabi

Microstructure evolution of MeB2 (Me = Zr, Ti) powders prepared by borothermal reduction of the corresponding oxides with boron under vacuum was investigated after heat-treatment at different temperature. The existence of the by-product B2O3 resulted

Liquid-phase-sintered SiC ceramics (LPS-SiC) with the sintering additives of Y2O3–Al2O3 and Y2O3–Al2O3–TaB2 were prepared. The oxidation behaviours of these sintered SiC ceramics were studied after oxidation test at 1300 °C in air. In comparis

Effect of in-situ -formed TaB 2 additives on ZrB 2 powders synthesized by borothermal reduction of ZrO 2 with boron together with a small amount of Ta 2 O 5 , and their densification were studied. Without TaB 2 additives, coarse ZrB 2 powders were pr

Sintered reaction-bonded Si3N4 ceramics with equiaxed microstructure were prepared with TiO2–Y2O3–Al2O3 additions by rapid nitridation at 1400°C for 2 hours and subsequent post-sintering at 1850°C for 2 hours under N2 pressure of 3 MPa. It was
