Alumina, also known as aluminum oxide (Al2O3), is the most mature and commonly used technical ceramics. With excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness. Alumina content ranging from 80% to more than 99% according to different application.
It's widely used in automotive, petro-chemical, fluid control, material transfer, industry, electrical and electronic, semiconductor,etc...
