Aluminum Oxide – Zirconium Oxide (Al₂O₃-ZrO₂) Ceramic Substrate is a composite material combining aluminum oxide and zirconium oxide. This blend creates a substrate with enhanced toughness, thermal stability, and wear resistance. The addition of zirconium oxide improves the fracture toughness and mechanical strength of the material, making it suitable for applications requiring high durability and thermal resistance, especially in electronics, automotive, aerospace, and medical fields.
These substrates are typically a mixture of aluminum oxide (Al₂O₃) and zirconium oxide (ZrO₂) in varying ratios, tailored to balance the thermal and mechanical properties. Zirconia generally comprises about 10–20% of the composition, reinforcing the aluminum oxide matrix with increased toughness.
Enhanced Toughness: The addition of Aluminum Oxide – Zirconium Oxide significantly improves fracture toughness, making the composite substrate more resistant to cracking and mechanical stress than pure aluminum oxide.
High Hardness and Strength: The composite retains the high hardness of aluminum oxide, with added durability from zirconium oxide, which contributes to better impact resistance and a longer service life under demanding conditions.
High Thermal Stability: These substrates withstand high temperatures, with the combination of Aluminum Oxide – Zirconium Oxide offering stability up to 1600°C (2912°F) or more, depending on the exact composition.
Improved Thermal Shock Resistance: The addition of ZrO₂ enhances the material’s ability to withstand rapid temperature changes, reducing the risk of thermal cracking, which is advantageous in applications involving extreme or fluctuating temperatures.
Excellent Dielectric Properties: Aluminum Oxide – Zirconium Oxide (Al₂O₃-ZrO₂) substrates provide excellent electrical insulation, making them suitable for applications in electronics where reliable isolation of electrical components is required.
Low Dielectric Loss: This property is particularly beneficial for high-frequency applications, as it minimizes power loss and enhances performance.
Chemical Inertness and Corrosion Resistance: The Aluminum Oxide – Zirconium Oxide (Al₂O₃-ZrO₂) composite is highly resistant to chemical attacks, including exposure to acids, alkalis, and other corrosive environments, making it suitable for use in challenging industrial and chemical processing settings.
Power Electronics: The high mechanical strength, thermal stability, and electrical insulation properties make these substrates ideal for power electronics, where they dissipate heat and protect components in high-power circuits and modules.
Automotive and Aerospace Components: The toughness and thermal resistance make Al₂O₃-ZrO₂ substrates suitable for sensors, ignition systems, and high-temperature components in automotive and aerospace applications.
Medical Devices: These biocompatible, wear-resistant substrates are used in medical devices and implants, offering durability and corrosion resistance in demanding biological environments.
Optics and High-Precision Instruments: The smooth surface and thermal stability of these substrates make them useful as mounting bases in optical systems, laser equipment, and other high-precision instrumentation.
