Technical Specifications

Material Introduction:

Key Characteristics of Alumina Ceramic:

Exceptional Purity & Electrical Insulation: High-purity alumina (e.g., 96%, 99.5%) offers excellent electrical insulation, preventing
current leakage and protecting sensitive microelectronics.

High Thermal Stability & Conductivity: It maintains structural integrity at extreme temperatures while effectively dissipating heat, 

crucial for processes like chemical vapor deposition (CVD) and etching.

Superior Mechanical Strength & Hardness: It provides excellent wear resistance and rigidity, ensuring long-term dimensional stability 

and durability under mechanical stress.

High Vacuum Compatibility: Alumina has very low outgassing rates, making it ideal for the ultra-high vacuum (UHV) environments 

required in deposition and lithography chambers.

Excellent Plasma Resistance: It withstands corrosive plasma environments during etching and cleaning processes without generating 

contaminants.
Key applications are found in the following sectors:

1. Semiconductor Manufacturing
This is one of the most demanding and critical application areas. Alumina's purity and performance are essential 
for chip fabrication.

Electrostatic Chucks (ESCs): Used to hold silicon wafers firmly in place using electrostatic force during lithography, etching, and deposition 

processes. They require excellent flatness, thermal conductivity, and electrical insulation.

Wafer Handling Components: Robotic end-effectors, alignment pins, and lift pins that directly contact wafers. Their wear resistance and smooth 

surface prevent contamination and particle generation.

Process Chamber Components: Plasma etch shields, focus rings, and gas distribution plates (showerheads). These parts resist corrosive plasmas 

and high temperatures while maintaining precise geometries.

Heating Elements & Insulators: Used in high-temperature furnaces and process chambers for thermal insulation and structural support.

2. Electronics & Electrical Engineering
Leveraging its superb dielectric strength and thermal management capabilities.

Substrates & Insulators: The primary material for thick-film and thin-film electronic circuits, providing a stable, insulating, and thermally conductive 

base for electronic components.

RF Microwave Windows: Used in vacuum tubes, klystrons, and magnetrons to transmit microwave energy while maintaining a vacuum seal.

Spark Plugs & Ignition Tubes: The insulating body that contains the central electrode, withstanding high voltages and extreme thermal cycling.

3. Industrial & Mechanical Applications
Valves, Seals, and Wear Parts: Used in pumps and valves handling abrasive slurries, corrosive chemicals, and high-

pressure fluids. Their hardness provides exceptional wear resistance.

Cutting Tools: Alumina-based ceramic inserts are used for high-speed machining of cast iron, nickel-based superalloys, and other hard materials.

Textile Guides: Wire guides, eyelets, and thread guides in textile machinery benefit from alumina's smooth, wear-resistant surface that minimizes 

friction and fiber damage.

4. Medical & Healthcare

Biomedical Implants: Used for orthopedic applications like hip joint prostheses and dental implants due to its biocompatibility, high compressive strength, 

and wear resistance.

Surgical Instruments: Components for specialized surgical tools where electrical insulation, sterility, and chemical resistance are critical.

5. Automotive

Sensor Components: Used in oxygen sensors (lambda sensors) located in the exhaust system to monitor oxygen levels. It withstands high exhaust temperatures 

and corrosive gases.

Engine Components: Wear-resistant parts, seals, and insulators within high-performance or advanced propulsion systems.
Typical Semiconductor Applications:

Wafer Processing: Electrostatic Chucks (ESCs), Wafer Handling Arms, Focus Rings, Gas Distribution Plates (Showerheads), Plasma Etch 

Chambers.

Inspection & Metrology: Vacuum Chucks for wafer probing, stages for lithography and inspection tools.

Process Support: Heater Susceptors, Insulating Standoffs, Alignment Pins, Viewport Windows.
