Abstract: (2368 Views)
Ceramic borides, carbides and nitrides with high melting point, relatively good resistance to oxidation and corrosive environments are considered by many researchers in various high temperature industries, which is known from the family of materials as high temperature ceramic (UHTC). To be. All UHTCs have very strong bonds that give them structural stability at high temperatures, and among them diboride compounds offer the highest degree of oxidation resistance, which compared to carbides and nitrides, diborides have high thermal conductivity and their strength Increases against heat shock. Further studies on diborides, especially zirconium diboride (ZrB2), were selected as the most promising candidate for use in high temperature applications. This review article discusses their mechanical and thermal properties, especially ZrB2, and also focuses on the effect of additives such as SiC to improve mechanical or thermal properties and / or to improve oxidation resistance in harsh environments at temperatures above 2000 ° C.
