· JVASP-34679· TiAs2O7

TiAs₂O₇ is a titanium arsenate ceramic compound belonging to the family of mixed-metal oxide ceramics. This material is primarily of research and specialized industrial interest rather than a commodity engineering ceramic, with applications driven by its unique chemical and thermal properties in demanding environments. The arsenic-titanium oxide system is investigated for potential use in high-temperature applications, nuclear waste immobilization, and specialized optical or electronic devices where its specific crystal structure and chemical stability offer advantages over conventional alternatives.
