The unique properties of ZrB2-based ceramics are suitable for ultra-high temperature structural applications such as re-entry space vehicles, hypersonic vehicles, and propulsion systems. Monolithic ZrB2 is associated with challenges during processing and sintering, limiting its widespread application, in addition, its physical and mechanical properties degrade at above 1200 °C due to its critical oxidation resistance. These problems are partially addressed by adding carbides, like SiC and ZrC, into ZrB2 ceramic. The synthesis and sintering of ZrB2-based ceramics are much more accessible than monolithic ZrB2, resulting in overall better performance. The present review focuses on the processing route and sintering techniques of ZrB2-based binary, ternary ceramics and composite and their effect on physical and mechanical properties. Also, novel advanced processing and fabrication techniques of ZrB2-based materials are mentioned. This research article tackles the drawbacks and challenges present in the existing literature and how a sustainable approach can rectify these issues.
