Advanced Alumina Ceramic Substrate

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

High Hardness & Wear Resistance - Mohs hardness of 9 (second only to diamond), ideal for wear-resistant components, cutting tools, and bearings.
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).
Excellent Electrical Insulation - High resistivity and low dielectric loss, suitable for electronic substrates and insulating parts.
Chemical Inertness - Resistant to acids, alkalis, and corrosion; biocompatible for medical implants (e.g., artificial joints).
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.
