中文摘要：

采用固相反应法制备了（RbBi）1/2MoO4陶瓷样品。室温下测量了（RbBi）1/2MoO4的红外反射谱,观察到15个振动模式;利用Kramers-Kronig（K-K）关系对样品的红外反射谱进行数据处理,获得材料的光频介电常数ε∞=2.17,微波频段的外推值为20.56,略小于实际测量值21.4;获得材料的本征品质因数Q×f为11 790GHz,高于实际测量值6 200GHz,说明陶瓷材料的品质因数还有较大提升空间。

英文摘要：

The（RbBi）1/2MoO4 ceramic was prepared via solid state reaction method.The room temperature far-infrared reflectivity spectra were measured and 15 vibration modes were observed.Kramers-Kronig（K-K） relationship was employed to fit infrared spectra.The optical frequency permittivity ε∞ is equal to 2.17 for the dielectric materials,and the extrapolated value to microwave frequency（at about 9 GHz） is 20.56 and it is slightly smaller than the actual measured value ～21.4.The calculated value of quality factor（Q×f） is 11 790 GHz,which is higher than the actual measured value ～6 200 GHz,and it can be deduced that the quality factor of the（RbBi）1/2MoO4 ceramic material has large room for improvement.
