· JVASP-9616· TaBO4

Tantalum borate (TaBO4) is a ceramic compound combining tantalum and boron oxides, belonging to the class of mixed-metal borates. This material is primarily of research and specialized industrial interest rather than a high-volume commodity ceramic. TaBO4 and related tantalum borates are investigated for high-temperature structural applications, refractory systems, and potential use in advanced electronic or optical devices where tantalum's chemical stability and boron's glass-forming properties can be leveraged together.
