· JVASP-21050· Sr2B2O5

Sr2B2O5 is a strontium borate ceramic compound belonging to the borate glass-ceramic family, characterized by a crystal structure containing strontium and boron oxide phases. This material is primarily investigated in research contexts for thermal and optical applications, including potential use in high-temperature insulation systems, glass-ceramics processing, and specialized optical coatings where borate chemistry offers tailored thermal expansion and chemical durability. The strontium borate system is notable for its lower processing temperatures compared to traditional silicate ceramics, making it relevant for applications requiring moderate thermal stability without the processing complexity of fully sintered oxides.
