摘要:
采用放电等离子烧结技术制备了锌掺杂铝酸镁透明陶瓷,研究了烧结温度对透明陶瓷的微观结构、光学性能和微波介电性能的影响. 结果表明:当烧结温度低于1 325 ℃时,陶瓷试样的致密度随烧结温度的升高逐渐增大,直线透过率呈相同趋势变化,1 325 ℃时直线透过率达到最大值为70%;随烧结温度进一步升高,致密度和直线透过率减小;透明陶瓷的介电常数值介于8.19至8.54之间,品质因数值在1 325 ℃达到最大值 66 000 GHz, 谐振频率温度系数值变化较小,其值介于-73×10-6/℃至-65×10-6/℃之间.
Abstract:
The zinc-doped magnesium aluminate transparent ceramics were prepared by spark plasma sintering technology. The influences of sintering temperature on the microstructure, optical and microwave dielectric properties of zinc-doped magnesium aluminate transparent ceramics were studied. The experimental results indicate that the density and the in-line transmittances increase with the increase of the sintering temperatures when the sintering temperature is lower than 1 325 ℃. The in-line transmittance at the wavelength of 550 nm reaches the maximum of 70% at 1 325 ℃. However, the density and the in-line transmittances decrease with the further increase of the temperature. When the dielectric constant maintains between 8.19 and 8.54, the values of quality factor reaches a maximum of 66 000 GHz at 1 325 ℃. The temperature coefficient of resonance frequency value is independent of the sintering temperature and remains between -73×10-6/℃ and -65×10-6/℃.
