Er2B4C

Er₂B₄C is an erbium-based ceramic compound combining rare-earth, boron, and carbon constituents. This material belongs to the family of rare-earth borocarbides, which are primarily investigated for high-temperature structural applications and specialized functional uses where thermal stability and chemical resistance are critical. While still largely in the research phase, Er₂B₄C and related borocarbides show promise in aerospace and extreme-environment contexts where conventional ceramics face limitations.
