· Ba2 Si8 O18

Ba₂Si₈O₁₈ is a barium silicate ceramic compound belonging to the silicate glass and ceramic family, characterized by a high silica content with barium as a network modifier. This material is primarily investigated in research contexts for high-temperature structural applications and optical components, where its thermal stability and silicate backbone offer potential advantages in demanding environments; barium silicates are also explored for specialized glass-ceramic systems, refractory applications, and as precursors in glass manufacturing where they can improve melting characteristics and thermal performance compared to conventional silicates.
