摘要

Abstract

Transition metal borides have contributed to the success of ultrahigh-temperature materials (UHTM) development. Current ZrB

- and HfB

-based UHTMs exhibit high-temperature environmental stability

high strength and modulus but inevitable brittleness due to strong covalent bonding. In contrast but interestingly

is predicted as a ‘ductile’ and soft ceramic for ultrahigh-temperature applications

through density functional theory investigations on its electronic structure and bonding properties. The ‘ductility’ is underpinned by chemical bonding anisotropy

that is

a strong

bond connecting the B

octahedra and a weak banana bond formed by overlapping the lobes of two perpendicular

orbitals (τ bond).
