The overall goal of this program is to explore the chemical and traditional synthesis, processing and microwave dielectric properties of novel ceramics in the system tantalum oxide-zirconium dioxide. The investigation will be conducted to gain deeper insights into the fundamental relationships between the atomic level defects, heterogeneous interfaces and dielectric properties. The measurement results of quality factor, dielectric constant and temperature coefficients of these properties will be correlated to the observed microstructure and the far infrared reflectance spectra. The program will establish the collaboration with engineers and scientists from industries and National Institute of Standards and Technology (NIST). The proposed work will explore the fundamental understanding and relationship between the atomic level defects, heterogeneous interfaces and microwave dielectric properties and its temperature dependence. The program will establish the collaboration with industries and government laboratories (NIST).

该计划的总体目标是探索新型陶瓷的化学和传统合成、加工和微波介电性能，这些陶瓷是在钽氧化物-二氧化锆系统中的。这项研究将更深入地了解原子级缺陷、非均质界面和介电性质之间的基本关系。这些性质的品质因数、介电常数和温度系数的测量结果将与观察到的微结构和远红外反射光谱相关联。该计划将与工业界和国家标准与技术研究所(NIST)的工程师和科学家建立合作关系。这项工作将探索原子能级缺陷、异质界面和微波介电性质之间的基本理解和关系及其与温度的关系。该计划将与行业和政府实验室(NIST)建立合作。
