Ceramic Zirconia Powder [-270+400]

Thermal Spray Grade Zirconia Powder

Zirconia-based ceramic coatings are widely specified for their thermal barrier properties, chemical inertness, and resistance to high-temperature wear. The -270+400 mesh particle size distribution is a common requirement for achieving consistent powder flow, controlled melting, and optimal coating density in automated thermal spray operations.

This powder is typically processed via agglomerated and sintered or fused and crushed manufacturing routes to ensure the correct morphology for reliable feeding. The resulting coatings exhibit excellent hardness and a low coefficient of friction, making them suitable for protecting parts in pumps, valves, aerospace components, and industrial machinery.

Process Compatibility and Selection

Selecting the correct powder grade is critical for coating performance. The -270+400 mesh cut is generally preferred for processes requiring a finer particle distribution to achieve a smooth as-sprayed surface finish. While this powder is compatible with multiple thermal spray processes, the optimal choice depends on your specific coating requirements, substrate material, and equipment setup.

• HVOF (High Velocity Oxy-Fuel): Produces very dense, well-bonded coatings with low porosity.
• Plasma Spray: Offers flexibility for a wide range of ceramics and is suitable for thick thermal barrier coatings.
• Flame Spray: A cost-effective option for less critical wear applications and dimensional restoration.

We recommend discussing your application parameters with our technical team to confirm the ideal powder specification for your process.
