· JVASP-25593· CaAl2B2O7

Calcium aluminum borate (CaAl₂B₂O₇) is a ceramic compound belonging to the borate ceramic family, characterized by a crystal structure combining calcium, aluminum, and borate phases. This material is primarily investigated for high-temperature applications and optical/thermal management systems where borate ceramics offer advantages in chemical durability and thermal stability. Its selection over traditional alumina or silicate ceramics is driven by specialized requirements in refractory applications, optical components, and composite reinforcement where borate chemistry provides enhanced properties.
