1. Strength: ZTA boasts a high compressive strength of up to 2500 MPa, making it one of the strongest ceramics available on the market. This property makes it ideal for applications where high loads and stresses are encountered.
2. Toughness: The addition of zirconia to alumina increases the material’s toughness, making it more resistant to cracking and fracturing. This property is crucial for applications where the ceramic may be subjected to impact or thermal shock.
3. Wear Resistance: Alumina is known for its exceptional wear resistance, and the addition of zirconia further enhances this property. ZTA exhibits a low coefficient of friction and high resistance to abrasion, making it perfect for applications where the ceramic may be in contact with other materials and subjected to wear.
4. Corrosion Resistance: Both zirconia and alumina are highly resistant to corrosion, and the combination of these materials in ZTA results in a ceramic that is resistant to a wide range of chemicals and environments. This property makes ZTA suitable for use in various industries, including chemical processing, oil and gas, and mining.
5. Thermal Stability: ZTA has a high melting point of around 2200°C, making it suitable for use in high-temperature applications. Additionally, the material exhibits low thermal expansion, ensuring that it maintains its dimensions and properties during thermal cycling.
6. Electrical Properties: ZTA is an excellent electrical insulator, with a high dielectric strength and low dielectric loss. This property makes it suitable for use in electronic and electrical applications where high-voltage insulation is required.
