A new analytical technique to characterize the physical and chemical properties of materials in the "over thousand degree centigrade" (OTD) region, a complex impedance spectroscopy using flames (OTD-CIS) was proposed. Since the flames have electric conductivity, they can be used as an electric probe instead of conventional metal electrodes that are interactive with samples in the OTD region. Intrinsic electric properties of the flame, rectification in DC characteristics and a response of positive ions in AC characteristics required specific experimental and analytical techniques to obtain OTD-CIS spectra, i.e., frequency response measurement using a pulsating voltage and a differential analysis to eliminate the background response of the flame. By using these techniques, OTD-CIS was successfully demonstrated for an aluminum oxide (Al2O3). Although the dielectric constant of Al2O3 in the OTD region was not changed from that at room temperature, the resistivity was continuously reduced in the OTD region.
