· Ce5Si3N9

Ce5Si3N9 is a rare-earth silicon nitride ceramic compound combining cerium oxide with silicon nitride, designed to enhance high-temperature structural performance. This material is primarily of research and developmental interest for advanced ceramic applications requiring improved thermal stability, oxidation resistance, and mechanical properties at elevated temperatures, particularly in aerospace and energy sectors where it competes with conventional silicon nitride and other rare-earth doped nitride ceramics.
