The infrared and far-infrared waves radiate inside the ceramic by microwave heating of the magnetic ceramicWhen we heat the magnetic materials by microwaves, the temperature of the magneticmaterials rises and infrared and far-infrared waves emit. At the same time, spins ofmagnetic materials are transited by not equilibrium state of thermodynamics andthe wavelength of microwaves is transformed to infrared and far-infrared waves with awavelength ２．３μｍ～２０μｍ and it emits beyond the intensity of ideal black bodyradiation.The emission energy is shown in the following equation (4) ２πμＢｒｆ ２ １ Ｐ＝（ ） ｈωｎ （4） ｈ ２π⊿ωＰ;the energy of radiation,μ;magnetic moment,Ｂｒｆ ;magnetic field,ｈ;planck constant,⊿ω；transit frequency,ω; frequency of radiation,ｎ ;number of atoms that are transited

Microwave heating of Mn-Zn-Ca ferriteWe add 10% Ca in Mn-Zn ferrite and make Mn-Zn-Ca ferrite.We sinter the Mn-Zn-Ca ferrite inside the ceramic and heat it in amicrowave oven. The electric dipole momentum of Ca is transited andspins of Ca atoms by the magnetic field of Mn-Zn ferrite are transited.Mn-Zn-Ca magnetic ceramic emits infrared and far-infrared waves witha wavelength of 8 μm to 50μm, extending to 100μm so calledTerahertz region.
When we irradiate microwaves to the Mn-Zn-Ca ferrite, the electric dipoleof Ca is transited.

The power of emission of the magnetic ceramic with a wavelength of 8μm to 100μm by electric dipole and magnetic dipole transition is calculated from equation (5) and (6) and it is shown in the figure below. The power ofemission with wavelength range 8μm to 100μm is amplified beyond the range of ideal black body radiation.
The absorption wavelengths of Calcium or Calcium Apatites were shown by B.O. Fowler in theNational Institute of Dental Research in U.S. in 1973. We show his data in Figure. From this data, the absorption wavelength of Ca is between 8μm and 50μm or 100μm, Terahertz region. Data from Inorganic Chemistry, Vol.13, No.1,1974

Weheat quarts glasses of 100cc of water which contain different Ca concentrations and pure water using these ceramics in the microwave oven and we measure their temperature rise and ion values as we show the experimental set up in Figure

The conclusions of the experimentsThe high concentration Ca waters showthe highest microwave heating effectswhile using Mn-Zn-Ca (Ca10%) ferrite andthe high concentration Ca waters alsoshow higher heating effects while usingMn-Zn ferrite. The higher ion values showhigher heating effects. The infraredemission wavelength from Mn-Zn-Caferrite coincides with the Ca absorptionwavelength between 8μm and 50μm or100μm and synchronizes with this.
