Yttria Stabilized Zirconia Spherical Powder Description

Yttria Stabilized Spherical Powder is a precision-engineered ceramic powder designed for consistent performance in plasma and flame spray applications. Its perfectly spherical particles ensure smooth powder flow and uniform deposition, making it ideal for creating dense, adherent coatings. The stabilized zirconia structure resists phase degradation and maintains mechanical integrity under extreme thermal stress. This makes it a reliable choice for protective coatings in gas turbines, high-speed aerospace assemblies, and thermal shielding systems exposed to rapid heating and cooling cycles.

Yttria Stabilized Zirconia Spherical Powder Features

• Excellente résistance aux chocs thermiques: Maintains structural stability under rapid temperature fluctuations, ideal for thermal barrier coatings in extreme environments.
• Stable Phase Composition: Partially stabilized with 8% yttria, the powder retains a mix of cubic and tetragonal phases that prevent unwanted transformation at high temperatures.
• Spherical Particle Morphology: Uniformly round particles improve flowability and coating uniformity in thermal spraying systems.
• High Wear and Corrosion Resistance: Offers strong resistance to erosion, oxidation, and corrosive gases at elevated temperatures, extending coating life.
• Faible conductivité thermique: Effectively insulates underlying substrates, protecting metal components in high-heat conditions like turbines and rocket engines.

Yttria Stabilized Zirconia Spherical Powder Applications

• Thermal Barrier Coatings (TBCs): Used in jet engines, turbines, and combustion chambers to shield metal components from extreme heat.
• Composants aérospatiaux : Applied to wing surfaces, flame tubes, and exhaust nozzles for insulation and thermal fatigue resistance.
• Energy Sector Equipment: Protects surfaces in high-temperature industrial processes, including plasma furnaces and boilers.
• Automotive Turbochargers: Acts as a heat-protective coating in high-performance engines.
• Rocket Propulsion Systems: Serves as a key insulating material in nozzle and combustion zone coatings.

Yttria Stabilized Zirconia Spherical Powder Packaging

Yttria stabilized zirconia spherical powder is typically packaged in sealed, moisture-proof plastic bags, then placed in sturdy drum containers or fiber cartons to prevent contamination and ensure safe transport. Standard packaging sizes include 1 kg, 5 kg, and 10 kg options, with custom packaging available upon request to meet specific usage or storage needs.
