• Large transparent single crystals of NaVO_3 were grown by the Czochralski method. The complex dielectric constant was measured in a frequency range between 100 Hz and 3 MHz from room temperature to 500℃. Two dielectric dispersions were found. A remarkable dispersion observed only along the c-axis obeys the formula of the Debye-type with a single relaxation time. The temperature dependence of relaxation time is summarized as τ(T)=τ_0exp(E/kT), where E=0.67 eV and τ_0=3.0×10^<-12>sec, respectively. This relaxation phenomenon may be due to impurities and vacancies.
