Influence of Lithium Substitution for Zinc on Crystal Structure and Microwave Dielectric Properties of Willemite Li2x Zn2−x GeO4

“…Figure 3b shows the FWHM and Raman shift of A g (2) peaks of all compositions with increasing x value and sintered at their optimum temperatures. FWHM value is inversely correlated to the lifetime of the phonon, and the narrower peak corresponds to the longer lifetime of phonon and less interaction with phonons.…”

“…In the last decades, microwave dielectric materials have experienced enormous progress with a wide range of applications in filters, resonators, substrates, and antennas, etc. 1,2 The recent advances in wireless communication and information systems have stimulated the development of new materials and technologies. One of the development directions is the high-frequency dielectric materials for the next generation communication system such as the Tactile Internet (5G wireless systems) and Internet of Things (IoTs).…”

“…One of the development directions is the high-frequency dielectric materials for the next generation communication system such as the Tactile Internet (5G wireless systems) and Internet of Things (IoTs). [1][2][3] For better frequency selectivity, high filter performances, and reduced insertion loss, low dielectric losses (tan δ) or high Q values (Q = 1/tan δ) are crucial for the development of novel materials that can be used at high-frequency bands. [4][5][6] It is well known that the factors that influence Q value can be divided into intrinsic and extrinsic ones.…”

Influence of cation order on crystal structure and microwave dielectric properties in xLi4/3Ti5/3O4-(1-x)Mg2TiO4 (0.6 ≤ x ≤ 0.9) spinel solid solutions

“…In recent years, wireless communication systems have experienced enormous growth, leading to increasing demand for base materials such as microwave ceramics for applications in cell phones, radar, satellite broadcasting, and glob positioning systems [1][2][3]. Microwave dielectric ceramics are used to manufacture dielectric resonators, tubes, and microstrip lines, allowing microwave integration circuit (MIC) device sizes to be reduced to a millimeter scale.…”

NaCa4V5O17: A low-firing microwave dielectric ceramic with low permittivity and chemical compatibility with silver for LTCC applications

“…Thus, to achieve co-firing with inner metal electrodes (e.g. Ag), low sintering temperatures (< 961 o C, which is the melting point of Ag) should be satisfied along with chemical compatibility between ceramic matrix and electrodes [7][8][9][10].…”
