· JVASP-97866· CdSO3

Cadmium sulfite (CdSO3) is an inorganic ceramic compound belonging to the sulfite family of materials. While not commonly encountered in mainstream engineering applications, this compound is primarily of research interest in materials science and chemistry, particularly for studies involving cadmium chemistry, ceramic phase stability, and sulfite-based systems. Its use is limited in industrial applications due to cadmium's toxicity and environmental concerns, which have led to strict regulations on cadmium-containing materials in most developed economies.
