Industrial Ceramic Intriduction
Aluminium Oxide, Al2O3 is the most widely applied and cost
effective technical ceramic material. It offers a combination of
superior mechanical strength and electrical properties, wear
resistance and corrosion resistance. The maximum working
temperature is up to 1700 °C with relatively high thermal
conductivity. It is also an electrically insulating material with a
high electrical resistivity. The good corrosion resistance makes it
insoluble in water and slightly soluble in strong acid and alkaline
solution.
