1.1 Advantages
Better electrical conductivity, compared with Zn/Al film
Considerable good self-healing performance
Good performance of anti-air-corrosion. Convenience for reserve and long storage time
1.2 Disadvantage
1.2.1 higher capacitance loss than Al/Zn film
1.2.2 coated lay is very thin, so metallikon is difficult.
1.2.3 In time of metal spraying, alumina will increase the resistivity.

2. Application
Applied to capacitors for power system, refrigerators, air conditioners and so on.
