Aluminium nitride ceramics
AlN ceramics have excellent comprehensive performance and have very wide application foreground in many areas . It is perfect for semiconductor chip and structure of packaging material. A enormous potential application in the electronics industry.AlN ceramics are also high temperature resistance , corrosion resistance and not erosion by variety of molten metal and molten hydrochloric.So it can be used for high grade refractory and crucible materials. Also can be used for anticorrosive coating,for example back boxing of vessel which put the corrosive substance.High purity is transparent and can be used for electronic optics . Also have excellent wear resistance which can be used for abrasive substance and resistant to wear and tear parts.
