Characteristic
Zinc phosphate is an inorganic compound with the formula Zn3(PO4)2)(H2O)4. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment. One common agent is sodium pyrophosphate.
Chemical formula:H4O12P2Zn3
Molar mass: 454.11 g/mol
Appearance: white solid
Density: 3.998 g/cm3
Melting point :900 °C (1,650 °F; 1,170 K)
Solubility in water:insoluble
Magnetic susceptibility (χ):−141.0·10−6cm3/mol
Refractive index (nD):1.595
Crystal structure:monoclinic
Application
Zinc phosphate hydrate is used in dentistry. It is commonly used for luting permanent metal restorations and as a base for dental restorations. Zinc phosphate cement is also used for cementation of inlays, crowns, bridges, and orthodontic appliances and occasionally as a temporary restoration.
