Aluminium Oxide Ceramic Material

Time enhances the tribological properties and the material allows excellent surface finishing.

Aluminium oxide ceramic material. Oxide ceramics aluminum oxide al 2 o 3 the most well known oxide ceramic material. Alumina or aluminum oxide al 2 o 3 in its various levels of purity is used more often than any other advanced ceramic material. 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. Aluminum oxide al 2 o 3 ceramic properties.

Alumina is the most well known and most commonly used fine ceramic material. The traditional ceramics that we. Ceramtec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. Alumina is one of the most cost effective and widely used material in the family of engineering ceramics.

Ceramtec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. Al 2 o 3 is an electrical insulator but has a relatively high thermal conductivity 30 wm 1 k 1 for a ceramic material. This tiny off white bobbin is a ceramic called aluminium oxide but it is nothing like your ordinary china mug type ceramic. It has the same sintered crystal body as sapphire and ruby.

Aluminium oxide is insoluble in water. This material is so hard that once it s been fired and sintered it has to be cut using diamond tooling. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.

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. According to iso 6474 alumina for biomedical applications must reach 99 5 purity level and have a sio 2 and metal oxide content lower than 0 1. Alumina commonly known as aluminium oxide al 2 o 3 is an inert odourless white amorphous material often used in industrial ceramics due to its outstanding properties alumina has contributed to a significant number of life extending and society enhancing applications. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

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. The most well known oxide ceramic material alumina or aluminum oxide al 2 o 3 in its various levels of purity is used more often than any other advanced ceramic material. In its most commonly occurring crystalline form called corundum or α aluminium oxide its hardness makes it suitable for use as an abrasive and as a component in cutting tools. Aluminium oxide is responsible for the resistance.
