· SrB4O7

Strontium tetraborate (SrB4O7) is an inorganic ceramic compound combining strontium oxide with borate glass-forming chemistry. It is primarily investigated in research contexts for applications requiring thermal stability and optical properties, particularly in phosphor systems, scintillator materials, and specialized glass-ceramic compositions where borate chemistry provides glass-forming capability and strontium contributes to luminescent or thermochemical functionality.
