Tube cylindrique en céramique d'alumine à structure multicouche empilée is a high-performance inorganic non-metallic material product, made from high-purity alumina (Al ₂ O3) powder through isostatic pressing, high-temperature sintering, and precision machining processes. Its core design is a multi-layer concentric cylindrical stacking structure, which significantly improves the mechanical strength, thermal stability, and functional integration of ceramic tubes through interlayer interface optimization and material gradient distribution technology.
Product Features:
High strength and wear resistance: alumina content ≥ 95%, hardness above HRA88, bending strength ≥ 350MPa, suitable for high load and strong friction environments.
Excellent thermal performance: high temperature resistance (operating temperature ≥ 1600 ℃), low coefficient of thermal expansion (7.2 × 10 ⁻⁶/℃), outstanding thermal shock resistance (Δ T ≥ 300 ℃ cycling without cracks).
Stabilité chimique : resistant to acid and alkali corrosion (except hydrofluoric acid), suitable for environments with strong corrosive media.
Structural advantages: Multi layer stacking design can disperse stress and reduce the risk of cracking; Functional materials (such as conductive and heat-insulating coatings) can be embedded between layers to achieve composite functionality.
Usinage de précision : Inner/outer diameter tolerance ≤ ± 0.05mm, cylindricity ≤ 0.02mm, supports customized aperture, wall thickness, and surface treatment (polishing, coating, etc.).
Core application scenarios
This product, with its high performance and structural designability, is widely used in the following fields to solve pain points that traditional materials find difficult to balance:
Équipement de fabrication de semi-conducteurs
Application: As a wafer transfer chamber, vacuum suction cup, or heater base.
Solution: Replace metal components to avoid metal contamination; Multi layer structure achieves thermal uniformity control and reduces warpage caused by thermal stress on the wafer.
High temperature industrial furnaces and heat treatment equipment

Solution: Resistant to high temperature oxidation and thermal shock, extending service life; Multi layer insulation structure reduces energy consumption and improves thermal efficiency.
Chemical and Environmental Protection Fields
Application: Corrosive fluid transport pipelines, reactor liners, or catalyst carriers.
Solution: Replace stainless steel or plastic pipes to resist strong acid and alkali corrosion; High surface finish reduces medium retention and lowers pollution risk.
New Energy and Power Electronics
Application: Fuel cell electrolyte separator, solid-state battery packaging tube or high-voltage insulation sleeve.
Problem solving: High insulation (volume resistivity ≥ 10 ¹⁴Ω· cm) and airtightness ensure equipment safety; Multi layer conductive/insulating layer integration simplifies structural design.
Aerospace and Precision Instruments
Application: Missile nozzle, infrared window bracket, or optical component base.
Problem solving: Balancing lightweight (density 3.9g/cm ³) with high rigidity; Low thermal expansion coefficient reduces deformation errors caused by temperature changes.
