Microstructure of ZrB2–ZrN directionally solidified eutectic composite by arc-melting
Journal of Asian Ceramic Societies, 2018 A ZrB2–ZrN eutectic composite was prepared by arc-melting a mixture of ZrB2 and ZrN powders under a N2 atmosphere. The eutectic composition was 48ZrB2–52ZrN (mol%), resulting in a rod-like microstructure comprising hexagonally faceted ZrN single-crystal ...

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.ABSTRACT A multilayer coating system was developed as an ablation and thermal protection measure for C/C composites. The multilayer coating architecture consists of SiC, ZrB2‐SiC (ZBS), and ZrC‐ZrO2 (ZZC) sublayers with a Sm2O3‐ZrO2 (SZC) topcoat.

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
