Product Name:Zinc Phosphate
Chemical Formula: Orthophosphate (common hydrated form): Zn3(PO4)2·4H2O (tetrahydrate), Anhydrous form: Zn3(PO4)2
Molecular Weight:Tetrahydrate: ~ 458.17 g/mol,Anhydrous: ~ 386.09 g/mol
CAS Number: Anhydrous: 7779-90-0, Tetrahydrate: 7543-51-3
Appearance:White crystalline powder or granules, odorless and tasteless.
Density:~ 3.99 g/cm³ (anhydrous).
Solubility:Practically insoluble in water; slightly soluble in dilute mineral acids (e.g., hydrochloric acid, sulfuric acid); insoluble in ethanol and alkaline solutions.
Melting Point:Decomposes at high temperatures without a distinct melting point (typically loses water of crystallization and decomposes into zinc oxide and phosphoric acid when heated).
Main Applications
Coatings and Anticorrosion:
Widely used as a rust-inhibiting pigment in paints, lacquers, and primers. It replaces traditional toxic lead or chromate pigments by forming a stable zinc phosphate-metal surface film (chemical passivation layer) to inhibit corrosion, suitable for substrates like steel and galvanized sheets.
Commonly applied in automotive coatings, marine anticorrosion, and steel structure protection.
Pharmaceuticals and Dentistry:
Used in dental materials to prepare zinc phosphate cement, a temporary or permanent adhesive for dental restorations. It utilizes its acidic curing property to bond with tooth structures.
Industrial and Chemical Fields:
Serves as a flame retardant or filler in plastics, rubber, and coatings, suppressing combustion reactions by releasing phosphoric acid.
Acts as an intermediate for synthesizing other zinc compounds (e.g., lithium zinc phosphate) and is used in electrolysis, ceramic glazes, etc.
Agriculture and Animal Husbandry:
Used in small amounts as a feed additive to supplement zinc and phosphorus for animals (dosage must be strictly controlled).
Safety and Protection
Toxicity:
Low toxicity, but dust may irritate the eyes and respiratory tract. Ingestion may cause gastrointestinal discomfort.
Protective Measures:
Wear dust masks, protective goggles, and gloves during operation to avoid inhaling dust or contacting skin/mucus membranes.
Storage:
Store in a sealed container in a dry, ventilated place, away from strong acids and bases.
Environmental Impact:
Zinc is a heavy metal; avoid untreated wastewater discharge to prevent water pollution.
Standards and Specifications
Industrial grade standards: e.g., zinc content (as ZnO) ≥65%, water-soluble salts ≤1.0%, etc.
Pharmaceutical grade standards: Must comply with pharmacopoeia requirements, with strict limits on impurities (e.g., heavy metals, arsenic).
