Review: high-entropy borides-challenges and opportunities

High-entropy borides are deemed robust candidates because of their complex combination of entropy-driven, multi-component disordered solid solutions. They are particularly remarkable for their unique single-crystal structures and significant bandgap. This structural adaptability positions them uniquely among materials, setting them apart from conventional transition metal diborides. Researchers have been fascinated by the appeal of high-entropy borides for a long time, driven by the groundbreaking idea of 'High entropy ceramics'. Nevertheless, the lack of thorough review papers in this field has hindered the progress of creating strong and durable high-entropy borides. This paper proposes adopting a collaborative strategy to properly negotiate this unexplored region. This perspective covers the up-to-date research on successfully synthesized high-entropy boride complexes. It examines compositional strategies, historical backgrounds, structural complexity, fabrication methods, mechanical, thermal, and oxidation properties, as well as emergent properties with potential uses, pathways, and future possibilities. This attempt challenges materials science traditions by introducing novel materials with superior performance. [GRAPHICS] .
