Ceramics Alumina Oxides

Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications.

Ceramics alumina oxides.

This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Aluminum oxide ceramic or alumina is the preferred nonmetal choice for many structural ceramic components and high voltage insulators. Alumina oxide ceramics al2o3 is the most widely used fine ceramics material.

Alumina ceramic is relatively inexpensive readily obtained and has metallization schemes compatible with the user friendly 94 to 97 compositions that can be commercially obtained. Ceramtec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. It has been used for decades in electrical components for its high electrical insulation and is widely used in mechanical parts for its high strength and corrosion and wear resistance. Aluminium oxide al2o3 or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications.

Alumina is the most well known and most commonly used fine ceramic material. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. It has the same sintered crystal body as sapphire and ruby. Aluminas aluminum oxide al 2 o 3 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.

Zirconia ceramics have the advantages over alumina ceramics of higher fracture toughness and higher flexural strength and relatively lower young s modulus although after a number of implant failures the choice of zirconia components in hip procedures suffered a significant setback. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
