A novel approach for manufacturing of layered, ultra-refractory composites using pliable, short fibre-reinforced ceramic sheets

Journal of Advanced Ceramics, 2023
A new additive technique for manufacturing of short fibre-reinforced ultra-refractory ceramics is presented. This technique allows the fabrication of solvent-free, thin (~100 µm), flexible, and easy-to-handle sheets suitable for fabricating homogeneous ...

Transient liquid-phase to guide multiphase evolution in reactive-hot-pressed ZrB2–SiC–ZrC ceramics

Journal of Materiomics, 2020
In reactive-hot-pressed ZrB2–SiC–ZrC ceramics, ZrO2 was found to replace ZrC phase, hence leading to confusion in designing ultra-high-temperature ceramics (UHTCs).

Advances in Transient-Liquid-Phase Bonding of Ultra-high Temperature ZrC Ceramics

High Temperature Materials and Processes, 2012
Full exploitation of the many attractive engineering properties of ultra-high temperature ceramics (UHTCs) requires that they can be joined. This paper explores progress in identifying joining strategies based on the use of transient liquid phases (TLPs).

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.

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 ...

Fabrication and microstructure of ZrB2–ZrC–SiC coatings on C/C composites by reactive melt infiltration using ZrSi2 alloy

Journal of Advanced Ceramics, 2018
ZrB2–ZrC–SiC ternary coatings on C/C composites are investigated by reactive melt infiltration of ZrSi2 alloy into pre-coatings. Two different pre-coating structures, including porous B4C–C and dense C/B, are designed by slurry dip and chemical vapor ...
