| 20090230125 | Technological development for carrying out cooking and chemical reaction, chemical synthesis, metalworking, metal cyrstallization, metal sintering and metallurgy by heating pottery with microwave for converting into far infrared or infrared wave radiation from pottery with increased heat efficiency - A method of heating a substance has not made much progress unlike rapid scientific developments. Although many studies have been made on the optimum heating temperature of a material, heating is not recognized in terms of the heat absorbing wavelength of a substance to be heated. Microwave heating provides a heating method by means of the friction heat of molecules, and microwave is separately absorbed to a magnetic element or the like and radiated by having its wavelength converted into a far infrared or infrared wave region can be controlled by a magnetic element's Curie temperature, a radiated wavelength region can be controlled within a specific temperature range, and heat energy increases when its density is increased. When, based on a principle of blackbody radiation, a magnetic element, magnetite, aluminum oxide, zirconia, zeolite, and the like applied to pottery is used microwave oven, high temperature can be obtained simply and in a short time without using an electric furnace thus enabling a wide application to chemical experiments. It has been learned that when this technology is used in microwave ovens used in homes across the country for cooking, delicious foods can be cooked simply and quickly even by elderly persons or children without using direct firing. Microwave heating using pottery started 15 years ago, but it has been left difficult to solve with little theoretical background. Magnetic element heating by microwave is beyond a classical physics idea region. Without being dependent on a classical physics theory uses a quantum mechanical effect that a magnetic element is irradiated with microwave and microwave is absorbed due to the spin resonance of magnetic element to radiate infrared rays. A combination of quantum mechanical theory by microwave irradiation to magnetic element and far infrared radiation effect by Planck's black body radiation is a key to this technology. | 09-17-2009 |
