Alumina

ALUMINA OVERVIEW

Family Overview

Aluminas (aluminum oxide, Al₂O₃) are the most commonly used technical ceramics due to their generally useful properties and good price/performance ratio. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80% to more than 99%. Higher purity alumina demonstrates enhanced wear and corrosion resistance — creating a continuous scale of various alumina grades, compositions, and performance.

Aluminas are used in both general use and specialized applications. A grade is selected to fit the application environment. Alumina compositions and microstructures can be formulated to meet the specific performance requirements of more demanding applications. 

• General use
• Wear resistance
• Electrical insulator
• Dielectric strength
• Low dielectric loss
