ALUMINUM OXIDE CERAMIC
Alumina Ceramics (Al₂O₃) - A Technically Important Oxide Ceramic Material
Aluminum oxide ceramic (Al2O3) is the technically most important oxide ceramic material with the widest use. Densely sintered aluminum oxide has high resilience and hardness, temperature stability, high wear resistance and corrosion protection even at high temperatures.
These artificially produced materials with an aluminum oxide content of more than 80% to over 99% have proven themselves in practical use. The choice of material is determined by technical and economic aspects. However, a material with a higher alumina content may not best meet the application requirements.
The mechanical properties of aluminum oxides from different producers can also differ with the same aluminum oxide content due to different powder recipes.
Aluminum oxide materials meet all the requirements for insulating material in electrical engineering. Excellent property values for flexural strength, wear resistance and temperature resistance are recommended for mechanical applications.
Alumina ceramics can differ significantly in their microstructure and thus in their properties.
Surfaces with the greatest possible material content are not always necessary or desirable. For thread guides for the textile industry z. B. The contact area of the yarn should be small and have no sharp points, while for sealing washers a material content of about 80% is required.

PROPERTIES ALUMINUM OXIDE CERAMIC
ALUMINUM OXIDE CERAMIC CUSTOMER PARTS
Due to the good price-performance ratio and the versatile properties, aluminum oxide ceramics are used, among other things, in the sanitary industry as sealing elements. In the electrical industry it is used as an insulating element, in electronics as a substrate, in mechanical and plant engineering as wear protection (wear-resistant material). In the chemical industry, it is used as a protection against corrosion (corrosion-resistant material that is largely resistant to vapours, melting and slag up to high temperatures) and as a filter material. In measurement technology, it is used as a protective tube for thermocouples in high-temperature measurements, in human medicine as an implant and in high-temperature applications as burner nozzles or as support tubes for radiators.
