Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. CeramTec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. Examples of applications for aluminum oxide Al2O3 advanced ceramics are heavy-duty forming tools, substrates andresistor cores in the electronics industry, tiles for wear protection and ballistics, thread guides in textile engineering, seal and regulator discs for water taps and valves, heat-sinks for lighting systems, protection tubes in thermal processes orcatalyst carriers for the chemicals industry.
Very different types of multiphase ceramics can be produced with different properties by varying the type and quantity of raw materials.
Silicate ceramic components are used in electronics and electrical engineering and act as electrical insulation in fuses, circuit breakers, thermostats and in lighting technology. The ability of silicate ceramic materials to provide thermal insulation is also utilized in heating, environmental and thermal engineering applications. Porous components are produced for the emission of fragrances and insecticides, as carriers for catalysts or for various applications in laboratories.
Non-oxide ceramics, such as Aluminum nitride (AlN) is the only technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. This makes aluminum nitride predestined for use in power and microelectronics applications. For example, it is used as a circuit carrier (substrate) in semiconductors or as aheat-sink in LED lighting technology or high-power electronics.
