Er2 Re2 Si2 C1

Er₂Re₂Si₂C is an experimental rare-earth transition metal silicide carbide ceramic belonging to the family of high-entropy or complex ceramic compounds. This material combines erbium (rare earth), rhenium (refractory metal), silicon, and carbon to explore enhanced thermal stability, oxidation resistance, and mechanical performance at elevated temperatures. Such multinary ceramics are primarily under investigation in research settings for next-generation aerospace and energy applications where conventional carbides or silicates reach their performance limits.
