· JVASP-13350· TaBi3O7

TaBi3O7 is a complex ternary oxide ceramic composed of tantalum and bismuth, belonging to the family of mixed-metal oxides studied primarily in materials research. This compound is not widely commercialized in mainstream engineering applications but represents an active area of investigation for its potential in high-performance ceramic systems, particularly where bismuth-containing oxides offer advantages in thermal, electrical, or photocatalytic properties. The material's notable density and stiffness characteristics make it relevant to researchers exploring dense ceramic phases for specialized applications such as photocatalysis, solid electrolytes, or high-temperature insulators.
