Core Advantages
Superior Flowability & Dispersion
The spherical shape minimizes interparticle friction, enabling seamless handling in 3D printing and powder metallurgy processes. This ensures uniform layer deposition in additive manufacturing, resulting in high-strength, defect-free components . Compared to lamellar zinc powders, spherical particles exhibit 20% better flowability , reducing agglomeration in coatings and composites.
Enhanced Corrosion Protection
In zinc-rich primers, our powder forms a dense, continuous protective layer on steel surfaces. Its sacrificial anode properties sacrificially corrode to shield the substrate, offering 20+ years of anti-corrosive performance for marine structures and industrial equipment . Salt spray tests demonstrate 50% longer corrosion resistance compared to traditional zinc flakes .
High Reactivity & Catalytic Efficiency
The large specific surface area (e.g., 45 m²/g for 30 nm powder ) accelerates chemical reactions, making it ideal for use as a reducing agent in pharmaceuticals and battery electrolyte formulations. Its nano-scale reactivity also enhances the cycling stability of zinc-ion batteries, enabling 4,700+ hours of operation at high current densities .
Applications
Coatings: Used in galvanizing, zinc-rich paints, and anti-fouling marine coatings to protect steel from corrosion .
Energy Storage: Critical component in zinc-air batteries and next-gen zinc-ion batteries, enhancing energy density and cycle life .
Additive Manufacturing: Enables precise 3D printing of complex metal parts with high dimensional accuracy .
Chemical Industry: Serves as a catalyst in organic synthesis and a reducing agent in pharmaceutical production .
Biomedical: Nano-scale powders with inherent antibacterial properties are explored for medical implants and wound dressings .
