Specifications of Refractory Fused Yttria Stabilized Zirconia Powder ZrO2 Zirconium Oxide Powder for Ceramic

Refractory Fused Yttria Stabilized Zirconia Powder (ZrO2) is a high-performance ceramic material designed for demanding industrial applications. The powder consists primarily of zirconium oxide stabilized with yttria (Y2O3), ensuring exceptional thermal and chemical stability. It is produced through advanced fusion processes, resulting in a pure, homogeneous product with minimal impurities. Typical purity levels exceed 99%, making it suitable for precision ceramic components.

The powder features a controlled particle size distribution, ranging from 1 micron to 50 microns. This allows flexibility in shaping and sintering processes. Fine particles enable smooth surface finishes in final products. Coarser grades provide structural integrity for bulkier components. The material’s high density (approximately 5.8-6.1 g/cm³) contributes to durability under extreme conditions.

Yttria stabilization prevents phase transitions during thermal cycling, maintaining dimensional stability up to 2000°C. This property is critical for applications exposed to rapid temperature changes. The cubic and tetragonal crystal phases enhance fracture toughness, reducing crack propagation. Low thermal conductivity (2-3 W/m·K) ensures effective insulation in high-temperature environments.

Chemical inertness makes the powder resistant to corrosion from acids, alkalis, and molten metals. It performs reliably in aggressive industrial settings. The material is compatible with standard ceramic forming techniques, including dry pressing, slip casting, and injection molding. Sintering temperatures typically range between 1400°C and 1600°C, yielding dense, high-strength ceramics.

Applications include thermal barrier coatings for aerospace engines, crucibles for metal melting, and wear-resistant components in machinery. The powder is also used in oxygen sensors, solid oxide fuel cells, and medical implants due to its biocompatibility. Custom particle size distributions and yttria content (3-8% Y2O3) are available to meet specific performance requirements.

Mechanical properties include high hardness (1200-1400 HV) and flexural strength (800-1200 MPa), ensuring longevity in abrasive environments. The material’s low wear rate extends the lifespan of tools and parts. It is supplied as a free-flowing powder, minimizing handling issues during production. Packaging options include moisture-resistant containers to preserve quality during storage and transport.

Applications of Refractory Fused Yttria Stabilized Zirconia Powder ZrO2 Zirconium Oxide Powder for Ceramic

Refractory fused yttria-stabilized zirconia powder (ZrO2 zirconium oxide powder) serves critical roles in advanced ceramic applications. This material stands out for its high melting point, thermal stability, and resistance to wear and corrosion. These properties make it ideal for industries requiring durable materials under extreme conditions.

In ceramics manufacturing, the powder enhances structural integrity. It is used to produce high-performance ceramic components like cutting tools, bearings, and valves. These parts operate in harsh environments, such as high-temperature furnaces or corrosive chemical settings. The addition of yttria stabilizes the zirconia structure, preventing cracks during heating or cooling. This stability ensures long-lasting performance in industrial equipment.

The powder also contributes to thermal barrier coatings. Applied to metal surfaces in aerospace and automotive engines, these coatings protect components from extreme heat. This extends the lifespan of turbine blades and engine parts. The low thermal conductivity of zirconia minimizes heat transfer, maintaining operational efficiency.

Another key application is in oxygen sensors and solid oxide fuel cells. The powder’s ionic conductivity at high temperatures enables precise oxygen level detection in automotive exhaust systems. In fuel cells, it facilitates efficient energy conversion by allowing oxygen ions to move freely. This supports cleaner energy solutions.

The medical field benefits from zirconia-based ceramics. Dental implants and prosthetics made with this powder offer biocompatibility and strength. Patients receive durable solutions that resist bodily fluids and mechanical stress. Similarly, orthopedic implants use zirconia ceramics for their wear resistance and compatibility with human tissue.

Electronics manufacturers use the powder in multilayer capacitors and insulators. Its electrical insulation properties ensure reliability in circuits and devices. The material’s stability under voltage fluctuations prevents failures in high-demand applications.

Refractory fused yttria-stabilized zirconia powder adapts to diverse industrial needs. Its role in improving product performance and durability remains unmatched. Industries prioritize this material for its ability to meet stringent technical requirements while reducing maintenance costs.

5 FAQs of Refractory Fused Yttria Stabilized Zirconia Powder ZrO2 Zirconium Oxide Powder for Ceramic

What is refractory fused yttria stabilized zirconia powder? This material combines zirconium oxide (ZrO2) with yttria (Y2O3) through high-temperature fusion. The process creates a stable structure resistant to cracking under heat changes. It’s used in high-performance ceramics needing strength and thermal shock resistance.

What industries use this powder? It’s common in aerospace, automotive, and industrial ceramics. Parts like turbine blades, engine components, and furnace linings rely on it. Medical tools and dental implants also use it for durability and biocompatibility. High-temperature kilns and metallurgy benefit from its heat resistance.

How does yttria stabilize zirconia? Pure zirconia changes structure when heated, causing cracks. Adding yttria prevents this. Yttria ions replace some zirconium in the crystal lattice. This keeps the material stable across wide temperature ranges. The result is a tougher ceramic that handles stress better.

Why pick this powder over others? It lasts longer under extreme conditions. It resists wear, corrosion, and thermal shock better than alumina or silica-based ceramics. Its low thermal conductivity makes insulation efficient. The fused process reduces impurities, boosting performance in critical applications.

How should the powder be stored and handled? Keep it dry in sealed containers. Moisture causes clumping and affects sintering. Use gloves and masks to avoid skin contact or inhalation. Process it in well-ventilated areas. Follow safety guidelines for oxide powders to ensure safe handling.
