摘要：

This paper reports that single-phase gamma-Y2Si2O7 is prepared via a sufficient blending and cold-pressed sintering technique from Y2O3 powder and SiO2 nanopowder. It studies the dielectric properties of gamma-Y2Si2O7 as a function of the temperature and frequency. The gamma-Y2Si2O7 exhibits low dielectric loss and non-Debye relaxation behaviour from 25 to 1400 degrees C in the range of 7.3-18 GHz. The mechanism for polarization relaxation of the as-prepared gamma-Y2Si2O7 differing from that of SiO2 is explained. Such particular dielectric properties could potentially make specific attraction for extensive practical applications.
