Zinc arsenate (Zn₂As₂O₇) is an inorganic ceramic compound containing zinc and arsenic oxides, belonging to the family of metal arsenate ceramics. This material is primarily of research and historical interest in ceramic chemistry and materials science, with limited modern industrial applications due to arsenic toxicity concerns; it has been investigated for specialized applications in glass formulation, ceramic pigments, and semiconductor-related research, though safer alternatives are preferred in most contemporary engineering contexts.
