Introduction

Alumina, commonly known as Aluminium oxide (Al2O3),  is usually a white or cream colored ceramics. It is a common and the most versatile engineered ceramic because of its high temperature service limit along with its chemical, electrical and mechanical properties. It is also relatively low cost, is easily formed and finished using a number of fabrication methods. It is often compounded with silica or trace elements to enhance its properties or fabrication and commonly will range from 92% to 99.999% Al2O3.

Alumina is also one of the most cost effective and widely used material in the family of Advanced Ceramics. The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes. With an excellent combination of properties and an attractive price, it is no surprise that technical grade alumina has a very wide range of applications.
