Ablation Properties of HfC–SiC–WC Ultra‐High Temperature Ceramics Produced by Pressureless Sintering

International Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
Schematic diagram highlighting the processes that occur during ablation testing of HfC–SiC and HfC–SiC–WC. ABSTRACT HfC–SiC is one of the leading thermal insulation ceramics that has the potential to perform well under high thermomechanical loads. In this study, we explore the use of pressureless sintering to produce this material at relatively low ...

Zirconium‐Based High Emissivity Multilayer Coating for Carbon/Carbon Composite With Enhanced Ablation Resistance

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

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

Advanced Science, Volume 13, Issue 19, 2 April 2026.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.
