Zirconia toughened alumina ceramic tube

Zirconia toughened alumina ceramic tube is a high-performance structural ceramic material. By uniformly dispersing zirconia (ZrO ₂) in the alumina (Al ₂ O3) matrix, the fracture toughness and mechanical strength of the material are significantly improved, while maintaining the inherent high hardness, wear resistance, and corrosion resistance of alumina.

Product features:
-High strength and toughness: The phase transformation toughening effect of zirconia significantly improves the bending strength and fracture toughness of ceramic tubes, effectively reducing the risk of brittle fracture.
-Excellent wear resistance: The hardness can reach Hv 1500 or above, suitable for high wear environments.
-High temperature resistance: It can work stably for a long time below 1200 ℃ and has excellent oxidation resistance.
-Chemical stability: resistant to acid and alkali corrosion, suitable for environments with strong corrosive media.
-Insulation performance: high resistivity, suitable for the electronics and power industries.

customized service
We provide comprehensive customized solutions to meet the special needs of different industries:

1. Customization of size and shape
   -We can produce ceramic pipes with an inner diameter of 1mm to 500mm and a length of 10mm to 2000mm, and support the processing of irregular pipes such as conical and corrugated pipes.
   -Provide precision machining services to ensure dimensional tolerances are controlled within ± 0.1mm.
2. Material ratio optimization
   -Adjust the zirconia content (5% -20%) according to application requirements, balancing toughness, hardness, and cost.
   -Other modifiers (such as MgO, Y ₂ O3) can be added to enhance specific properties.
3. Surface treatment and functionalization
   -Polishing treatment: reduces surface roughness (Ra ≤ 0.2 μ m), suitable for high-precision applications.
   -Coating strengthening: such as silicon carbide (SiC) coating, further enhancing wear resistance.
4. Connection and assembly plan
   -Provide metal ceramic composite pipe design to solve the problem of mismatched thermal expansion coefficients.
   -Support customized assembly requirements such as flange connections and threaded connections.

What problems can we solve?

1. Traditional ceramics are prone to brittle cracking: By using zirconia toughening technology, the impact resistance is significantly improved and the equipment failure rate is reduced.
2. Metal pipes wear out quickly: The wear resistance of ZTA ceramic pipes is 5-10 times that of high chromium steel, greatly extending their service life.
3. Material failure in high temperature environments: Its high temperature resistance makes it suitable for extreme working conditions such as metallurgy and energy.
4. Chemical corrosion causes equipment damage: Excellent corrosion resistance can replace materials such as stainless steel and plastic.
5. Contradiction between insulation and thermal conductivity requirements: It combines high insulation and moderate thermal conductivity to meet the dual requirements of heat dissipation and insulation for electronic devices.
