Comparison of Reactive and Non-Reactive Spark Plasma Sintering Routes for the Fabrication of Monolithic and Composite Ultra High Temperature Ceramics (UHTC) Materials [PDF]

Materials, 2013
A wider utilization of ultra high temperature ceramics (UHTC) materials strongly depends on the availability of efficient techniques for their fabrication as dense bodies. Based on recent results reported in the literature, it is possible to state that Spark Plasma Sintering (SPS) technology offers a useful contribution in this direction.

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
