20120024845 | EXOTHERMIC ENAMEL GLAZE, AND EXOTHERMIC CONTAINER COATED WITH SAME - The present invention relates to a heating vessel used in a microwave oven for cooking a food using a magnetron. In the heating vessel that is heated by absorbing some of a high frequency generated from the magnetron so that a food in the cooking room of the microwave oven can be cooked by a high frequency, the heating enamel glaze is fabricated, the fabricated heating enamel glaze is coated on the vessel made of metal material for enamel (a steel plate, aluminum, or stainless for low carbon enamel), dried, and then subjected to glassification plasticity and cooled, thus producing the heating enamel vessel for a microwave oven. Accordingly, the heating enamel vessel can withstand temperature higher than the existing heating vessel product (silicon rubber+ferrite) and can have high heating performance. In a method of fabricating the heating enamel glaze, ferrite (MnZn series, MgCuZn series, NiZn series) having high transmittance and metal soft magnetic material (Fe—Si series, Fe—Si—Al series, Fe—Si—B series Fe—Si—B—Co series, Fe—Ni series, etc.) alloy powder are mixed and added to a glaze (glassy frit) commercially used for enamel processing. Accordingly, the heating enamel glaze having a heating characteristic in which a microwave oven absorbs a microwave (2.45 GHz) and converts it into heat energy is fabricated. | 02-02-2012 |
