A unique cavity perturbation method has been used to study the dielectric behavior of chromium oxide (Cr2 O3) in the microwave region at ∼3.5 GHz and temperatures up to ∼1100 °C. The specimen in the form of pellet was heated by microwave power at 2.45 GHz in e-field of a single mode cavity. In the temperature range of measurement, the dielectric constant is found to increase within 10% and loss factor within one and a half times the room temperature values. Results are discussed in the light of agitated ionic motion in the material.
