The effect of hot-pressing temperature on the phase composition and properties of AlN–BN materials with addition of Y2O3 or SiC is studied. The composites have higher density and mechanical strength than the hot-pressed AlN–BN material without ad

The high-temperature oxidation of ZrB2–SiC and ZrB2–SiC–ZrSi2 ceramics up to 1700°C in air has shown their high corrosion resistance. A five-stage nonisothermal oxidation mechanism is established for the samples when heated at a rate of 20°C/

Thermal gravimetry and differential thermal analysis are used to study nonisothermal hightemperature oxidation of 56 wt.% ZrB2–44 wt.% MoSi2 and 86 wt.% ZrB2–14 wt.% MoSi2 ceramics in air up to 1600 °C. Oxide layers that form on samples at diffe

The paper examines the mechanochemical activation of starting minerals (kaolin, pyrophyllite, and talcum) and their effect on the solid-phase synthesis and properties of cordierite. Binary oxide compounds (spinel, mullite, enstatite, forsterite) are

Tribological properties are examined for composite materials based on titanium nitride under conditions of dry friction for a wide range of speeds (1–25 m/sec). It is shown that the composites have a high level of tribological properties, which may
