What's the Aluminum oxide

_{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.}
