China Yttria Stabilized Zirconia Powder from China - High-Toughness Ceramic Material by Top Suppliers & Factory Manufacturer, Supplier
Yttria Stabilized Zirconia (YSZ) powder is a premium advanced ceramic material, where yttria (Y₂O₃) is integrated into the zirconia (ZrO₂) crystal lattice. This incorporation effectively stabilizes the material, preventing phase transformation and endowing YSZ with remarkable thermal stability, high fracture toughness, excellent mechanical strength, and outstanding ionic conductivity. As a result, YSZ is capable of delivering reliable performance even in extreme thermal, mechanical, and chemical conditions. This makes YSZ one of the most sought-after functional ceramic materials in modern industries. As leading suppliers and a trusted factory based in China, we provide high-quality YSZ powder to meet various industrial needs
Aerospace Applications｜Thermal Barrier Coatings for Extreme Environments
YSZ is best known as the standard material for thermal barrier coatings (TBCs) in gas turbines and jet engines. When applied as a top coating on superalloy components, YSZ's extremely low thermal conductivity and high-temperature phase stability protect metallic substrates from excessive heat, significantly improving engine efficiency, durability, and service life. These advantages have made YSZ an indispensable material in the aerospace and power generation industries.
Energy & Sensing Technologies｜SOFC Electrolytes and Oxygen Sensors
Key Role: At elevated operating temperatures, YSZ exhibits high oxygen-ion conductivity while remaining electronically insulating — enabling efficient electrochemical reactions and stable power generation.
Another key application of YSZ powder is in solid oxide fuel cells (SOFCs), where it serves as the preferred electrolyte material. In addition, YSZ is widely used in oxygen sensors, particularly lambda sensors for automotive exhaust systems and industrial furnaces, where its oxygen-ion transport capability allows precise monitoring and control of combustion processes to improve efficiency and reduce emissions.
Extended Uses｜Structural, Dental, and Wear-Resistant Components
Beyond these primary applications, YSZ is also utilized in advanced structural ceramics, dental restorations, and wear-resistant components, benefiting from its strength, toughness, and long-term stability.
Production Method: Self-propagating hydrolysis process — ensuring high purity, uniform particle size distribution, and excellent sintering performance.
Our YSZ (Y-PSZ) powder is produced using a self-propagating hydrolysis process. By precisely controlling the yttria (Y₂O₃) content, we can supply different grades of Y-PSZ powder, with 3Y-PSZ as the standard product. Both compacted and non-compacted forms are available to meet customer requirements. The physical properties of our powders are suitable for a wide range of forming processes, providing customers with flexible and reliable processing solutions.
Q
What is YSZ powder and why is it used in thermal barrier coatings?
YSZ (Yttria-Stabilized Zirconia) powder is a ceramic material composed of zirconia (ZrO₂) stabilized with yttria (Y₂O₃). It is widely used in thermal barrier coatings (TBCs) because of its extremely low thermal conductivity and excellent high-temperature phase stability, which protect metallic superalloy components in gas turbines and jet engines from excessive heat, extending their service life and improving engine efficiency.
Q
What is the difference between 3Y-PSZ, 5Y-PSZ, and 8Y-PSZ grades?
The numbers refer to the molar percentage of yttria (Y₂O₃) content used to stabilize the zirconia. 3Y-PSZ (the most commonly used grade) offers the highest mechanical strength and toughness, making it ideal for structural and dental applications. 5Y-PSZ and 8Y-PSZ contain higher yttria content, providing improved phase stability at elevated temperatures and are preferred for thermal barrier coating and SOFC applications.
Q
How is YSZ powder used in solid oxide fuel cells (SOFCs)?
In SOFCs, YSZ powder serves as the electrolyte material. At high operating temperatures, YSZ exhibits high oxygen-ion conductivity while remaining electronically insulating. This property enables efficient electrochemical reactions between fuel and oxygen, allowing stable and clean power generation. Its chemical stability at elevated temperatures makes it the preferred electrolyte choice for SOFC systems.
Q
What forming processes are compatible with your Y-PSZ powder?
Our Y-PSZ powder is engineered to be compatible with a wide range of forming processes, including dry pressing, isostatic pressing, injection molding, tape casting, and slip casting. Both compacted and non-compacted powder forms are available, allowing customers to select the most suitable option for their specific manufacturing requirements.
Q
What purity levels does your YSZ powder achieve?
Our YSZ powder maintains very high purity levels. Key impurity limits include Al₂O₃ ≤ 0.01%, SiO₂ ≤ 0.01%, Fe₂O₃ ≤ 0.01%, CaO ≤ 0.005%, MgO ≤ 0.005%, TiO₂ ≤ 0.002%, Na₂O ≤ 0.005%, and Cl⁻ ≤ 0.01%. These stringent purity controls are achieved through our self-propagating hydrolysis production process, ensuring consistent quality and reliable sintering performance.
Q
Can YSZ powder be used for dental and medical applications?
Yes. YSZ powder, particularly 3Y-PSZ grade, is widely used in dental restorations such as crowns, bridges, and implant abutments. Its combination of high strength, excellent fracture toughness, biocompatibility, and aesthetic white appearance makes it a preferred material for dental ceramics. It is also used in advanced structural ceramics and wear-resistant components that require long-term dimensional stability and mechanical reliability.
