Porous curved alumina ceramic structural components

Product Introduction of High-Purity, Wear-Resistant, Porous Curved Alumina Ceramic Structural Components: Comprehensive Technical Characteristics and Industry Applications:

Ⅰ. Core Characteristics

1. Ultra-High Purity and Stability: Made from over 99% alumina (Al₂O₃) raw materials, achieving a density of 99% after high-temperature sintering.  The thermal expansion coefficient is as low as 7.6×10⁻⁶/℃, allowing for long-term stable operation in environments up to 1600℃.

2. Excellent Wear Resistance: Mohs hardness of 9 (close to diamond), with wear resistance more than 200 times that of stainless steel, suitable for high-wear applications such as mechanical sealing rings and bearing liners.

3. Controllable Porous Structure: Achieves 20%-75% porosity through pore-forming agents or gel casting technology, combining permeability and mechanical strength, suitable for applications such as filtration and catalyst carriers.

4. Precision Curved Design: Utilizing injection molding or 3D printing processes, supporting the customization of complex curved structures with a tolerance control of ±5μm and a surface roughness Ra<0.1μm.

Ⅱ. Application Scenarios

1. Industrial wear-resistant components: Such as ceramic rings for sand mills, with a lifespan up to 12 times longer than traditional metal parts.

2. High-temperature gas filtration: The porous arc-shaped structure improves gas-solid contact efficiency, used in chemical exhaust gas treatment.

3. Semiconductor equipment: High insulation (resistivity of 10¹⁴ Ω·cm) and low thermal expansion coefficient, suitable for wafer packaging requirements.

4. Biomedical applications: Excellent biocompatibility, used in artificial joints, with a friction coefficient of only 0.02.
