Description

Yttria Stabilized Zirconia (YSZ) is a high-performance ceramic material where zirconium dioxide (ZrO₂) is alloyed with yttrium oxide (Y₂O₃) to stabilize its desirable high-temperature tetragonal and cubic crystal phases. This stabilization is critical for preventing catastrophic phase transformations, granting the material exceptional thermal stability, mechanical strength, and ionic conductivity. It is an indispensable advanced material for demanding applications across the aerospace, energy, medical device, and industrial ceramics sectors, where reliability under extreme conditions is paramount.

Application

• Thermal Barrier Coatings (TBCs): A primary application for protecting superalloy components in gas turbine engines and jet aircraft from extreme heat.
• Solid Oxide Fuel Cells (SOFCs): Used as the electrolyte and electrode materials due to its high oxygen ion conductivity at elevated temperatures.
• Oxygen Sensors: Critical component in lambda sensors for automotive exhaust systems and industrial process control.
• Biomedical Implants: High-strength, biocompatible material for dental crowns, bridges, and orthopedic prosthetics.
• Advanced Structural Ceramics: Used in wear-resistant parts, cutting tools, grinding media, and precision engineering components.
• Catalyst Supports: Provides a stable, high-surface-area substrate for various catalytic processes.
• Electroceramics: Base material for capacitors, piezoelectric devices, and other electronic components.
• Abrasion-Resistant Coatings: Applied to industrial equipment and components to extend service life.

Quality Control

Our Yttria Stabilized Zirconia is manufactured under strict quality management systems. Each batch undergoes rigorous testing for critical parameters including phase composition (via XRD), yttria content, particle size distribution, and specific surface area. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are available upon request. We can supply grades tailored to meet various industry standards for technical, research, and advanced manufacturing applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect flowability and sintering properties.
