The Description of alumina ceramic tubes
Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to their outstanding property characteristics and cost-effective advantage. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped together based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, 99.9% alumina.Other types of alumina ceramic tubes
