Article

The behavior of ZrB2–MoSi2(SiC) and ZrB2–SiC–ZrSi2 ceramics under concentrated solar radiation is examined. The effect of zirconium silicide and molybdenum silicide admixtures on the formation of protective oxide layers on the ultrahigh-temperature ceramics in air at elevated temperatures is studied with the purpose of controlled development of dense protective films ensuring high service characteristics. The structure and composition of the oxidized materials are analyzed. The highest corrosion resistance is shown by the ZrB2–MoSi2 ceramics.
