Title:
EXOTHERMIC ENAMEL GLAZE, AND EXOTHERMIC CONTAINER COATED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2010/117137
Kind Code:
A2
Abstract:
The present invention relates to an exothermic container to be used in a microwave oven which cooks foods using a magnetron. The exothermic container absorbs a portion of the microwaves generated by the magnetron and generates heat to cook foods in the cooking chamber of the microwave oven. The exothermic container to be used in the microwave oven is produced by the steps of providing an exothermic enamel glaze, coating a metal container to be produced into an enameled container (low carbon steel plate, aluminum, and stainless steel to be produced into an enameled container) with the exothermic enamel glaze provided in the previous step, drying the resulting structure, firing the resulting structure to vitrify same, and cooling the resulting structure, to thereby achieve improved resistance against hot temperatures, improved exothermic performance, and higher quality as compared to conventional exothermic container products (silicon rubber and ferrite). A method for producing the exothermic enamel glaze involves mixing or adding (MnZn-based, MgCuZn-based, NiZn-based) ferrite, having high magnetic permeability, and alloy powders of (Fe-Si-based, Fe-Si-Al-based, Fe-Si-B-based, Fe-Si-B-Co-based, Fe-Ni-based, etc.) soft magnetic metal materials to the glaze (glass frit) commonly used in enameling, to thereby provide the glaze with exothermic properties for absorbing microwaves (2.45GHz) and for converting the absorbed microwaves into thermal energy in a microwave oven.
