Sodium arsenate (Na₃AsO₄) is an inorganic ceramic compound composed of sodium, arsenic, and oxygen, belonging to the family of metal arsenate salts. This material is primarily encountered in specialized industrial chemistry and environmental remediation contexts rather than mainstream engineering applications, where it functions as a reagent, precipitant, or component in glass and ceramic formulations. Its use is limited by the toxicity of arsenic and regulatory restrictions in most developed economies, though it retains relevance in legacy processes, analytical chemistry, and research into arsenic immobilization and waste treatment strategies.
