Calcium arsenate (Ca2As2O7) is an inorganic ceramic compound belonging to the arsenate family, characterized by calcium and arsenic oxide bonding in a crystalline structure. This material appears primarily in legacy applications and specialized research contexts, including historical pesticide formulations and ceramic waste management studies, though modern use is limited due to arsenic's toxicity concerns and regulatory restrictions. Engineers considering this material should recognize it mainly in remediation contexts, historical process understanding, or specialized research applications rather than as a primary choice for contemporary engineering designs.
