Institute of Metal Research, State Key Laboratory for Corrosion and Protection director Wang will represent the material depends on the pot may be used. On the market of non-stick pot is mainly three kinds of materials: aluminum, the surface layer of thick alumina; stainless steel, the surface layer of chromium oxide, corrosion resistance strong, corrosion slow; there iron, easily a large area by acid corrosion, thereby coating off. Wang stressed: "With the manufacture of non-stick corrosive metal such as iron, can not make acidic foods with anti-corrosive metal non-stick pan, try not to make acidic foods.."

      Using nano-ceramic as a non-stick coating, regardless of what kind of pot use does not corrode metal can achieve the effect, you can rest assured that the production of acidic foods.
