Technical Specifications: Why Alumina Ceramic Sheets Excel

Alumina ceramic sheets (Al₂O₃) are crafted from high-purity aluminum oxide, tailored to meet rigorous industrial standards. Key parameters include:

1)Thermal Performance:

●Heat Resistance: Operating range from -200°C to 1650°C, ideal for furnace linings, aerospace components, and thermal barriers.

●Thermal Conductivity: 25–30 W/m·K (superior to silicone or polymers), enabling efficient heat dissipation in electronics.

2)Electrical & Mechanical Properties:

●Dielectric Strength: Up to 33 kV/mm (99.7% purity), critical for high-voltage insulators and circuit substrates.

●Hardness & Wear Resistance: Mohs hardness of 9, bending strength ≥350 MPa, outperforming steel in abrasive environments.

3)Chemical Stability:

●Resists corrosion from acids, alkalis, and organic solvents, making them ideal for chemical processing equipment.

4)Customization Options:

●Available in purities (95%, 99%, 99.7%), thicknesses (0.5–30 mm), and surface finishes (polished, laser-cut, or coated).

Industry Applications: Real-World Case Studies

1. Electronics & Energy

●5G & RF Devices: Alumina ceramic sheets serve as low-loss substrates for 5G antennas, reducing signal interference with dielectric constants of 9.8–10.1.

●High-Power LED Cooling: Used as thermally conductive insulators in LED modules, slashing junction temperatures by 25% and extending lifespan.

2. Aerospace & Automotive

●Rocket Engine Insulation: NASA-grade alumina ceramic sheets line combustion chambers, enduring 1600°C exhaust gases without deformation.

●EV Battery Protection: Heat-resistant ceramic insulators shield battery packs from thermal runaway, meeting UL 94 V-0 fire safety standards

3. Industrial Manufacturing

●Steel Mill Wear Plates: Alumina ceramic sheets protect conveyor systems in steel plants, reducing downtime by 40% compared to steel plates

●Semiconductor Wafer Handling: Non-conductive, static-free sheets prevent contamination in cleanroom environments.
