摘要：

Influence of the test frequency, temperature and phase transition on the dielectric properties Of SiO2 composite materials was investigated. The dielectric constant and loss tangent were measured by high Q-cavity method at the frequency of X-band with the temperature range of 25 degrees C-1000 degrees C in the nitrogen atmosphere. Based on the componential and structural characteristics of the actual materials, the physical reason in essence for the variation of the dielectric properties was discussed according to the dielectric theory. The temperature influence the dielectric property of SiO2 composite materials was speculated to be 1500 degrees C based on the results of the XRD analysis from the room temperature to 1500 degrees C.
