Basic Information

Structural Information

• Structure Type: Inorganic crystalline compound, NASICON-type hexagonal zirconium phosphate ceramic material
• Structural Features: Three-dimensional network framework constructed by sodium zirconium phosphate. Silver ions are stably embedded in the lattice cavities. The practical crystalline formula is Ag0.5Na0.5Zr2(PO4)3·H2O, featuring stable lattice structure and slow ion release property.

Physical & Chemical Properties

• Appearance: White to off-white fine crystalline powder
• Particle Size: Average particle size approx 1 μm, cubic crystal form
• Melting Point: >500 °C, decomposes at high temperature
• Solubility: Insoluble in water and common organic solvents; stable in acidic and neutral aqueous environment
• Stability: Excellent thermal stability and oxidation resistance. The slow release of silver ions effectively reduces discoloration phenomenon during application.
• Silver Content: 3.5 ~ 4.0 wt%

Synthesis & Applications

Synthesis Method

1. Precipitation method: Mix sodium phosphate, zirconium salt and silver nitrate under controlled pH and temperature, perform precipitation, filtration, then calcine at 500–600 °C to obtain finished product.
2. Sol-gel method: Hydrolyze metal alkoxide raw materials to form gel, conduct ion exchange to load silver ions, followed by high-temperature calcination.
3. Solid-phase reaction method: Mix and grind raw materials including sodium phosphate, zirconium oxychloride and silver nitrate, then heat at 600–800 °C for solid-phase synthesis.

Main Applications

• Antimicrobial additives: Added into plastics, textiles and foams to inhibit bacteria and remove peculiar smell. Widely used in medical catheters, wound dressings and food packaging materials.
• Functional coatings: Used for preparing antibacterial paint and marine anti-fouling coatings.
• Catalyst materials: Applied as catalyst in oxidation and reduction reactions for fine chemicals and pharmaceutical synthesis.
