Abstract:

In the present paper, the sintering behavior and the THz absorption properties of B2O3 doped Ca [(Li1/3Nb2/3)0.95Zr0.15]O3 (CLNZ) ceramics are investigated. The results indicate that the sintering temperature of CLNZ ceramic can be significantly lowered by the doping of B2O3. The crystal structure evolution, phase assemblage as well as the microstructure properties are investigated by XRD and SEM respectively. The sintering mechanism is investigated based on microstructure analysis, where the liquid phase sintering is proposed to control the whole sintering process. The relative density of the B2O3 doped CLNZ ceramics possess the optimum value when the B2O3 doping content x is 1.5wt%. The THz absorption properties of B2O3 doped CLNZ ceramics sintered at 1020°C are investigated and are related to the microstructure, phase assemblage and crystal structure factors.
