Detailed Product Description

High Fracture Toughness 99% Al2O3 Ceramic Products

1. Description:

Most Alumina Ceramics are white but can be pink or brown. The different colors are derived from the additives during sintering as well as any impurities in the raw material. The majority of Alumina Ceramics have a purity level between 95 and 99 per cent. Higher purity Alumina Ceramics are perfect for environments where there is potential severe wear or may contain corrosive contaminates. Since Alumina Ceramics have excellent thermal stability, they can be used in areas that have drastic temperature changes.The chemical composition of Alumina Ceramics heightens its resistance to corrosion. Alumina is known as aluminum oxide, a hard wearing advanced ceramic that has been in use for years and is the most popular ceramic material for a variety of applications. The aluminum oxide in Alumina Ceramics is a form of bauxite, a white, brown, or red clay material first discovered in France in the early 19th Century and is commonly found in several locations around the world.
