ABSTRACT:
A heat-conducting mat for absorbing microwave and electromagnetic wave energy comprising: a basic metal material selected from the group including bronze, silver and soft iron, the basic metal material being pressed to form a piece of mat and capable to be rolled up; and a heat-conducting film being coated on the basic metal material; wherein the heat-conducting film comprising a heat-collecting coat comprising a first paste-like mixture of iron oxide powder, ruthenium, glass powder and medium; an electromagnetic wave energy absorbing coat comprising a second paste-like mixture of creaming gold, silver powder and the medium, the electromagnetic wave energy absorbing being printed and coated on the heat-collecting coat; and a protecting coat comprising a third paste-like mixture of iron oxide powder and glass powder, the protecting coat being coated on the electromagnetic wave energy absorbing coat so as to protect the basic metal material from generating static electricity or sparks. So that the piece of mat can be used for a microwave oven and an electromagnetic wave oven.
