Product Overview
Our Magnesia Stabilized Zirconia Ceramic Rod (Mg-PSZ) is a high-performance technical ceramic known for its exceptional mechanical properties and thermal shock resistance. Unlike other zirconia ceramics, Mg-PSZ offers superior toughness and stability at elevated temperatures, making it ideal for demanding structural applications. The material naturally presents a distinctive yellow color.
Key Features – Outstanding Performance
- High Fracture Toughness – Typical values 6–7 MPa·m¹/², providing excellent crack resistance.
- Excellent Thermal Shock Resistance – Withstands rapid temperature changes, suitable for furnace and high-heat environments.
- High Strength – Flexural strength > 250 MPa, compressive strength > 2500 MPa.
- Good Wear and Corrosion Resistance – Performs well in abrasive and chemically aggressive conditions.
- High Temperature Stability – Maintains mechanical properties up to 2100°C.
- Unique Yellow Color – Natural yellow appearance (no added pigments), consistent throughout the material.
