  • Patent number: 10154755
    Abstract: Disclosed are a method for manufacturing exothermic ceramics for a microwave oven and exothermic ceramics for microwaves. In particular, provided is a method for manufacturing exothermic ceramics for a microwave oven, in which the exothermic ceramics are formed by mixing a ceramic body, such as clay, plastic clay or soil, with an exothermic element prepared by combining at least one selected from silicon carbide, carbon ferrite and iron oxide, which are exothermic components. Accordingly, the exothermic ceramics of the present invention can minimize a sense of difference between the exothermic element and the ceramic body component, which is raw material for ceramics, thereby being capable of emitting high-temperature heat in a short time by means of microwaves as well as maintaining stability in the shape. Furthermore, due to integral forming, the exothermic ceramics have an enhanced elegant design.
