Abstract:
A coated glass ceramic cooking plate is provided, which has a multilayer coating on its lower surface. The multilayer coating includes a metallic layer of an alloy including components chromium, iron, nickel, and silicon. The silicon content of the alloy is at least 2 atomic percent. This metallic layer is covered by a barrier layer in form of an oxide of an alloy including components chromium, iron, nickel, and silicon, also with a silicon content of at least 2 atomic percent. The molar content of oxygen of the barrier layer is greater by at least a factor of 10 than that of the metallic layer.
