CHEMICAL STRUCTURE AND DESCRIPTION:
Tin Phosphate (Sn₃(PO₄)₂) is the phosphate salt of tin in the +2 oxidation state. It consists of three tin ions (Sn²⁺) and two phosphate ions (PO₄³⁻). It is insoluble in water but partially soluble in acids. It is used as an additive in the ceramics and glass industry, in pigment production, and in special catalytic applications. Tin compounds are valuable for producing heat-resistant and corrosion-resistant materials.
