Abstract EN
A fully dense TaC ceramic was prepared by hot pressing using 10 mol% ZrC plus 5 mol% Cu as a sintering aid.
Formation of (Ta, Zr)C solid solution (ss) by reaction between TaC and ZrC facilitated densification.
Addition of Cu refined the microstructure and consequently improved flexural strength of the TaC ceramics.
TEM investigation found ubiquitous precipitation of nanocrystallites at multigrain conjunctions.
The nanocrystallites were (Ta, Zr)C solid solution with uniform dispersion in an oxygen-rich glassy matrix.
Although formation of nanoprecipitates may not much affect the mechanical properties of the TaC ceramic, the structure suggested a new type of nanoceramic worth further research.
