Advantages
Chemical Resistance
They are highly resistant to chemical corrosion and can endure exposure to many aggressive chemicals, acids, and alkalis without degradation. This property is advantageous in chemical processing and the handling of corrosive substances.
High Hardness
Alumina ceramics are renowned for their exceptional hardness, ranking just below diamonds on the Mohs scale. This property makes them highly resistant to abrasion and wear, allowing them to maintain their integrity in demanding environments.
Excellent Mechanical Strength
They exhibit impressive mechanical strength, ensuring they can withstand heavy loads and mechanical stress without deformation or failure. This property is crucial in applications where structural integrity is paramount.
Exceptional Electrical Insulation
Alumina ceramics are excellent electrical insulators, making them indispensable in electronic and electrical applications. They can efficiently prevent the flow of electricity, making them suitable for insulating components and substrates.
Superb Thermal Stability
Alumina ceramics excel at maintaining their structural and mechanical properties at high temperatures, withstanding temperatures well above 1,000 degrees Celsius. This characteristic is invaluable in applications involving extreme heat.
Low Thermal Expansion
Alumina ceramics have a low coefficient of thermal expansion, meaning they do not significantly expand or contract with changes in temperature. This property contributes to their dimensional stability in varying thermal conditions.
