· Ca3P2

Calcium phosphide (Ca₃P₂) is an inorganic ceramic compound belonging to the phosphide family, characterized by its ionic bonding structure between calcium cations and phosphide anions. While primarily of research interest rather than established in high-volume industrial production, this material is investigated for applications requiring chemical reactivity with moisture and potential use as a precursor in phosphorus-based synthesis, particularly in semiconductor research and advanced ceramics development. Its notable property is high reactivity with water and oxygen, which limits conventional applications but makes it valuable for specialized chemical processing and as a starting material for deriving other phosphorus compounds.
