· JVASP-46798· Cr5Si4O14

Cr5Si4O14 is a chromium silicate ceramic compound belonging to the family of mixed-oxide ceramics. While not widely documented in mainstream engineering databases, materials in this compositional family are of interest in high-temperature and corrosion-resistant applications due to the combined benefits of chromium's oxidation resistance and silicate structures' thermal stability. Research into chromium silicates focuses on potential use in extreme-environment coatings, refractory systems, and specialized ceramic matrix composites where chemical durability and thermal performance are critical.
