· JVASP-60643· BiAsO4

BiAsO4 is an inorganic ceramic compound composed of bismuth, arsenic, and oxygen, belonging to the family of metal arsenate ceramics. While primarily of research interest rather than established industrial production, this material is investigated for applications requiring dense ceramic structures with potential uses in nuclear waste immobilization, photocatalytic devices, and specialized electronic components. BiAsO4 represents an understudied composition within the broader arsenate ceramic family, making it notable for researchers exploring novel ceramic phases with tailored physical and chemical properties.
