High Thermal Conductivity Alumina Ceramic Substrate 25 W/mK

Alumina Ceramic Substrates Revolutionizing the Electronics Industry

Alumina ceramic is an advanced ceramic material primarily composed of high-purity alpha-alumina (Al₂O₃). It exhibits outstanding physical, chemical, and mechanical properties, making it widely applicable in industries such as electronics, medical technology, and high-tech engineering.

Key Features & Advantages

1. High Hardness & Wear Resistance – Mohs hardness of 9 (second only to diamond), ideal for wear-resistant components, cutting tools, and bearings.

2. High-Temperature Stability – Melting point up to 2050°C, capable of long-term operation in environments up to 1600°C (e.g., furnace parts, aerospace components).

3. Excellent Electrical Insulation – High resistivity and low dielectric loss, suitable for electronic substrates and insulating parts.

4. Chemical Inertness – Resistant to acids, alkalis, and corrosion; biocompatible for medical implants (e.g., artificial joints).

5. High Mechanical Strength – Exceptional compressive strength, though relatively brittle; toughness can be improved via doping or composite techniques.

Common Applications

• Industrial – Sealing rings, nozzles, grinding media.

• Electronics – IC substrates, high-voltage insulators.

• Medical – Dental implants, surgical instruments.

• Energy & Environment – Fuel cell separators, wear-resistant pipelines.

Manufacturing Process

Produced via powder sintering (dry pressing, isostatic pressing, injection molding) followed by high-temperature firing (1500°C–1800°C). Purity ranges from 90% to 99.9%, with performance enhancing as purity increases.

Alumina ceramic remains a critical material in modern industry due to its unmatched combination of properties.
