“…The microwave dielectric properties ( Q × f value versus τ f ) of the reported ZnNb 2 O 6 ‐based MWDCs are summarized in Figure , and some typical systems are listed in Table . It is obvious that the current trilayered ZNO/TO/ZNO ceramics exhibit superior microwave dielectric properties than the available ZnNb 2 O 6 ‐based MWDCs.…”

A multilayer cofired architecture was proposed and demonstrated to achieve high-Q and temperature-stable microwave dielectrics in a derived system, Zn 1.01 Nb 2 O 6 -TiO 2 . This approach could effectively allow the chemical reactions between Zn 1.01 Nb 2 O 6 and TiO 2 occur at a rather narrow area (~12 μm), the interfaces of heterogeneous layers, where the diffusion of Zn, Nb, and Ti could be observed. Such interfaces could act as the in situ "glues" to connect each layer well. The effects of stacking scheme and TiO 2 content on the microwave dielectric properties of layered architectures were investigated systematically. The resonant frequency, Q-factor, and electric field distribution were reported using the eigenmode solver of high-frequency structure simulator. Among the available layer architectures, the optimized microwave dielectric characteristic was observed in Zn 1.01 Nb 2 O 6 /TiO 2 /Zn 1.01 Nb 2 O 6 stacked with 0.058 mol TiO 2 (~1.84 vol%).The τ f can be effectively tuned to approximately +0.53 ppm/°C, and importantly, a high Q × f value~99 500 GHz together with ε r~2 6.8 was achieved. This design could be beneficial for opening up new ways to develop high-performance microwave dielectrics based on current material systems and therefore to meet with the high requirements for 5G wireless communication components and multilayer packing technology.

“…The micromorphology is variable with the changing of temperature. When the sintering temperatures were less than 1450°C, the particles are composed of small crystal and the structure is not dense enough, which manifest that low temperature cannot provide enough energy for grain growth [17][18][19]. Raising the temperature again the samples surface becomes more compact and homogeneous and few grain boundaries appears.…”

CaTiO3-LnAlO3(Ln = La, Nd) ceramics were manufactured by reaction-sintering for produce low cost and high efficiency materials. Using reaction-sintering method to manufacture these ceramics, which have excellent comprehensive properties. The subtle variations on densification behavior, phase transformation, phase composition, microstructure evolution and performances of CaTiO3-LnAlO3(Ln = La, Nd) ceramics were studied systematically. The XRD pattern indicates that the Ca0.61La0.39Al0.39Ti0.61O3 phase and Ca0.7Nd0.3Ti0.7Al0.3O3 phase were generated under certain environmental conditions respectively. The ceramics exhibited excellent performance parameters: when εr is 42.03(45 635), the quality factor is 45500GHz (45 635) In addition, even in the environment of large temperature changes the ceramics can still maintain good performance. In conclusion, the reaction sintering method is an economic, convenient, available preparation means of making the CaTiO3-LnAlO3(Ln = La, Nd) ceramics and has broad prospects of application and development.

The explosive process of 5G communication evokes the urgent demand of miniaturized and integrated dielectric ceramics filter. It is a pressing need to advance the development of dielectric ceramics utilization of emerging technology to design new materials and understand the polarization mechanism. This review provides the summary of the study of microwave dielectric ceramics (MWDCs) sintered higher than 1000 from 2010 up to now, °C with the purpose of taking a broad and historical view of these ceramics and illustrating research directions. To date, researchers endeavor to explain the structure-property relationship of ceramics with multitude of approaches and design a new formula or strategy to obtain excellent microwave dielectric properties. There are variety of factors that impact the permittivity, dielectric loss, and temperature stability of dielectric materials, covering intrinsic and extrinsic factors. Many of these factors are often intertwined, which can complicate new dielectric material discovery and the mechanism investigation. Because of the various ceramics systems, pseudo phase diagram was used to classify the dielectric materials based on the composition. In this review, the ceramics were firstly divided into ternary systems, and then brief description of the experimental probes and complementary theoretical methods that have been used to discern the intrinsic polarization mechanisms and the origin of intrinsic loss was mentioned. Finally, some perspectives on the future outlook for high-temperature MWDCs were offered based on the synthesis method, characterization techniques, and significant theory developments.
