To counter shortcomings such as low thermal efficiency, oxidation, safety hidden trouble, this thesis made a sample including selecting material, burden and design of working technology for tradional electronic stove.Key heat property and line expanding cofficient of sample have been tested and analysed by scanning eletron microscope. Heat sample and test its thermal efficiency. Then contrast with traditional electronic stove. Production technology, structure and property have been studied in order to search for a new technology method with not only enhancing thermal conductivity of sample but also dropping its electrical conductivity and reducing its production cost.In the end, experimental result proved that those things influenced the last properties of sample. Those things includes pureness, granularity, composition of material ; pressure, method of molding and temperature, pressure, atmosphere, how long and measure of sinter.Based on cost factor, nature mineral is adopted as, which can satisfy the need of production technology. According to the physics character of material, it has finer insulation.
