摘要

采用非破坏性太赫兹时域光谱法测量了氧化铝陶瓷样品的介电常数。使用有效的介质近似，我们证明了相对介电常数可用于评估多孔氧化铝样品，孔隙率范围为0%至20% /体积。该结果可用于控制样品孔隙率，这是与压缩载荷下的机械强度、硬度和耐磨性或热稳定性相关的关键材料参数。

Non-destructive evaluation of ceramic porosity using terahertz time-domain spectroscopy

We measured the dielectric constants of alumina ceramic samples with non-destructive THz time-domain spectroscopy. Using an effective medium approximation, we demonstrated that the relative permittivity can be used to evaluate the porous alumina samples, with porosity fractions ranging from 0% to 20% per volume. This result can be used to control sample porosity, a key material parameter related to mechanical strength under compression load, hardness and wear resistance, or thermal stability.
