Alumina ceramic rods are made of Aluminum Oxide (Al2O3), often abbreviated as alumina, which is one of the world's most popular families for high performance technical ceramic materials. Coarse and dense alumina, which includes a range of qualities that are mainly of purity, is considered to be one of the best materials in terms of value for money. Alumina ceramics can then serve one of the widest industrial cross-sections of all oxide ceramics on the market.
Extremely high purity (max. 99.8%) Alumina grades can be produced using a selection of bonding and forming techniques (mixing, casting, pressing, etc.) to obtain a highly wear- and corrosion-resistant ceramic suitable for various applications. These properties can be mitigated and modified with a variety of additives and additional components, which are also available with a selection of adhesive solutions (cement, oxide, sinter, etc.).
