Zirconium diboride is widely applied to high-temperature materials, but it is easily oxidized at high temperature. To increase the oxidation resistance of zirconium diboride at high temperature, the A1(OH)3–Y(OH)3 is coated on the ZrB2 surface to prepare A1(OH)3–Y(OH)3/ZrB2 composite...

ZrB2 are widely applied because of some excellent performances; however, ZrB2 is easily oxidized in the high-temperature air. To reach better Al(OH)3–Y(OH)3 composite shell and higher coating ratio on the ZrB2 particles surfaces, ZrB2 particles must be adequately dispersed in the ZrB2...

ZrB2 belongs to a class of ceramics defined ultra-high-temperature ceramics with extremely high melting temperatures; however, ZrB2 ceramics is easily oxidized. To make ZrB2 ceramics possess the better oxidation resistance in the air at high temperature, in this paper, the effect of surface...

Silicon nitride (Si3N4) has attracted substantial interest because of its extreme chemical and physical properties, but the sintering densification of Si3N4 is difficult, and it is easily oxidized in the high-temperature air to impact high-temperature strength, which restricts its applied range....
