摘要：

A unique cavity perturbation method has been used to study the dielectric behavior of chromium oxide (Cr2O3) in the microwave region at similar to 3.5 GHz and temperatures up to similar to 1100 degrees 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. (c) 2007 American Institute of Physics.
