           What is alumina ceramic?
          Aluminium Oxide, Al2O3 is a major engineering material. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.
          Alumina can be produced in a range of purities with additives designed to enhance properties.
          Alumina can take temperatures up to 1650°C, having extremely high temperature stability, chemical corrosion resistance, and high wear and abrasion resistance.
