Background:

• Yttria-stabilized zirconia (YSZ) is a widely used ceramic material.
• Nickel (Ni) is a versatile metal with various industrial applications.
• Developing advanced composite materials with tailored structures is crucial for technological progress.

Purpose of the Study:

• To synthesize Ni-YSZ composites with a core-shell structure.
• To investigate the formation mechanism of these core-shell nanopowders.
• To characterize the structural properties of the synthesized YSZ@Ni composite.

Main Methods:

• Modified electroless plating process.
• Synthesis conducted at 65°C and pH 12.
• X-ray diffraction (XRD) analysis for structural characterization.

Main Results:

• Successfully produced YSZ@Ni core-shell nanopowders.
• YSZ nanoparticles were uniformly encapsulated by nickel.
• The nickel shell thickness was determined to be less than 20 nm.
• XRD confirmed the presence of both YSZ and Ni crystal phases.

Conclusions:

• The modified electroless plating is an effective method for creating YSZ@Ni core-shell nanostructures.
• The optimized conditions (65°C, pH 12) facilitate the formation of uniform nickel shells.
• The study provides insights into the formation mechanism of these novel composite nanopowders.
