Intrinsic Thermal Transport Properties of ZrB2 From Room Temperature to Melting Point

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Zirconium diboride (ZrB2) is a promising material for extreme‐environment applications, yet its intrinsic high‐temperature thermophysical behavior remains uncertain: Experiments are highly sensitive to processing conditions, simulations omit key mechanisms, and both rarely reach ultrahigh temperatures. Here, we predict the thermal conductivity
