Zirconium carbide (ZrC) is a potential coating, oxygen-gettering, or inert matrix material for
advanced high temperature reactor fuels. ZrC has demonstrated attractive properties for …

This paper presents the results of experimental investigations carried out on the synthesis of
pure ZrB2 by boron carbide reduction of ZrO2 and densification with the addition of HfB2 …

Densifications of hot-pressed ZrC ceramics with Zr and graphite additives were studied at
1800–2000° C. ZrC with 8.94 wt% Zr additive (named ZC10) sintered at 1900–2000° C …

Zirconium carbide has a wide range of substoichiometry facilitated by varying numbers of
carbon vacancies. Most experimental studies consider a solid solution of carbon and …

Three B 4 C-based composites with 10, 20 and 30 vol% ZrB 2-ZrC were prepared by
reactive hot-pressing of Zr and B 4 C powders at 1900° C for 2 h under 20 MPa in Ar …

Densification behavior, mechanical and thermal properties of ZrC 1− x ceramics with various
C/Zr ratios of 0.6–1.0 have been investigated by two-step reactive hot pressing of ZrC and …

Multi-phase ceramics in the TaC–TaB2–C system were prepared from TaC and B4C
mixtures by reactive pressureless sintering at 1700–1900° C. The pressureless densification …

Abstract C f/SiC-ZrB 2-Ta x C y composite was synthesized by reactive hot pressing (RHP) of
C f cloth, polycarbosilane (PCS), ZrB 2, and Ta powders at 4 MPa and 1200° C. PIP cycle …

Synthesis and densification of monolithic zirconium carbide (ZrC) has been carried out by
reactive hot pressing of zirconium (Zr) and graphite (C) powders in the molar ratios 1: 1 …

The sinterability of ZrC was enhanced by high-energy ball milling as well as introduction of
graphite and SiC as sintering additives. Densification process and microstructure …
