Application of alumina ceramic

Alumina ceramic (Al₂O₃ ceramic), known for its high hardness, insulation, and corrosion resistance, is widely used in automotive, electronics, industrial machinery, and medical fields. Its specific applications are as follows:

1. Automotive Industry

• Power Battery Systems: As ceramic-coated separators (alumina/nitride coating) and battery cover insulators. The coated separator raises the temperature resistance limit to 500°C, extending thermal runaway trigger time and improving battery safety; insulators prevent short circuits with high insulation and corrosion resistance (e.g., used in BYD blade batteries).

• Electronic Components: Used for alumina ceramic substrates in SiC MOSFET modules (for new energy vehicle electric drives). It reduces module volume by ~40% and enhances heat dissipation, ensuring stable operation of high-power components.

• Engine & Exhaust Parts: Manufactures valve guides and exhaust gas sensor housings. Its high-temperature resistance (long-term use up to 1600°C) and wear resistance adapt to the harsh environment of engines and exhaust systems.

2. Electronics & Electrical Field

• High-Precision Insulators: Applied in insulators for high-voltage switches, integrated circuit brackets, and LED lamp bases. Its high volume resistivity (≥10¹⁴ Ω·cm) and low dielectric loss ensure reliable electrical insulation and stable signal transmission.

• Semiconductor Equipment: Makes wafer carriers and plasma etching chamber liners. It is resistant to acid-base corrosion (withstands semiconductor cleaning agents) and high temperatures (adapts to 1200°C annealing processes), avoiding wafer contamination.

3. Industrial Machinery & Wear-Resistant Fields

• Wear-Resistant Components: Produces mechanical seals, ceramic bearings, and pump sleeves. With a Mohs hardness of 9 (second only to diamond), it has 3–5 times longer service life than metal parts, suitable for harsh conditions like slurry transportation and high-speed rotation.

• Grinding & Polishing Materials: Used as alumina ceramic grinding balls and sandpaper. It has high grinding efficiency and low wear, widely applied in polishing metal, glass, and semiconductor wafers.

4. Medical Field

• Biomedical Parts: Manufactures artificial joints (alumina ceramic femoral heads) and dental implants. It is non-toxic, has good biocompatibility (no tissue rejection), and high corrosion resistance (resistant to body fluid erosion).

• Medical Instruments: Makes high-precision instrument parts (e.g., syringe plungers, surgical instrument nozzles). Its smooth surface is easy to sterilize, avoiding cross-contamination.

5. Daily-Use & Other Fields

• Household Products: Produces alumina ceramic cutting tools (knives, scissors) and cookware. It is rust-proof, non-toxic (no metal ion precipitation), and easy to clean.

• Aerospace & Defense: Used for thermal insulation tiles and radar antenna covers. Its lightweight (density ~3.6 g/cm³)
