Abstract
Regular MgO nanoflowers were synthesized via a simple chemical route. The as-synthesized nanoflowers are single crystalline and consist of MgO nanofibers which have lengths up to several micrometers and diameters in the range of 20 – 80 nm , with an average of 50 nm . The frequency spectra of the relative dielectric constant and the dielectric loss were measured in the frequency range of 50 Hz to 5 MHz . Temperature spectra of the relative dielectric constant were also measured and the experimental results showed that MgO nanoflowers have a much higher relative dielectric constant as compared with MgO micropowders, especially at low frequencies at room temperature.Keywords
