· JVASP-12008· Zn2AsO4

Zinc arsenate (Zn₂AsO₄) is an inorganic ceramic compound belonging to the arsenate mineral family, formed from zinc and arsenate ions. While primarily studied in materials research rather than mainstream engineering, this compound has potential applications in specialty ceramics, particularly where arsenic-containing phases occur naturally or in controlled waste immobilization contexts. Its chemical stability and crystal structure make it relevant to researchers investigating arsenate-based ceramics and geochemists studying arsenic mineral behavior, though its use in commercial engineering applications remains limited due to arsenic toxicity concerns and availability of safer alternatives.
