Aluminum Oxide (Al2O3) is the most versatile and widely utilized high-performance ceramic, serving as a cornerstone in semiconductor manufacturing, chemical processing, medical technology, mechanical engineering, and the electronics industry.
As performance is directly dictated by material purity, Rauschert offers the Rapal® series with purity levels ranging from 99.6% to 99.9%. For applications requiring enhanced structural integrity, we also provide advanced composites the Rapal® AZ series, including Zirconia-Toughened Alumina (ZTA).

Key Characteristics & Benefits:

• Exceptional Hardness & Wear Resistance: Delivers superior durability and service life in high-friction environments.

• Superior Electrical Insulation: Maintains high resistivity and low dielectric loss under extreme voltage and temperature, making it the ideal choice for electronic packaging and substrates.

• High Mechanical Strength & Rigidity: Features outstanding compressive strength and a high modulus of elasticity to withstand significant mechanical stress.

• Outstanding Chemical & Corrosion Stability: Highly resistant to aggressive acids, alkalis, and solvents. As a non-oxidizing material, it maintains stable chemical properties even at elevated temperatures.
