“…substitution in the Zn 2 (Sn (1-x) Zr x )O 4 ceramics. The s f of the Zn 2 (Sn 0.99 Zr 0.01 )O 4 ceramics was less negative than that of the Zn 2 SnO 4 ceramics [8]. This is associated with dielectric constant and second phases.…”

“…Minor phases are hard to detect by XRD patterns. To identify the composition of the second phases, an EDS analysis was carried out on the grains of the Zn 2 SnO 4 ceramics [8]. Zn 2 SnO 4 is the main crystalline phase upon sintering at 1,175°C for 4 h, indicating that the ZnSnO 4 has formed in the initial stages.…”

“…Extrinsic loss is associated with the density, porosity, second phases, impurities, oxygen vacancies, grain size, and lattice defects [18,19]. The Q 9 f of Zn 2 SnO 4 and Zn 2 (Sn 0.99 Zr 0.01 )O 4 ceramics that were sintered at 1,225°C for 4 h was 39,000 and 87,000 GHz, respectively [8]. These results suggested that the Q 9 f improved by partially substituting Sn 4?…”

Zn 2 SnO 4 ceramics exhibit a dielectric constant of 10.2, a quality factor (Q 9 f) of 39,000 GHz, and a temperature coefficient of resonant frequency (s f ) of -84.3 ppm/°C when sintered at 1,225°C for 4 h [8]. A sintering temperature reduction of about 300°C had been obtained by replacing Mg 2?…”

Spinel CoZnTiO 4 ceramics were synthesized by conventional solid-state method and their microwave dielectric properties were investigated. The crystal structure and microstructures of specimens were studied by XRD and SEM. The CoZnTiO 4 phase forms at a temperatures ranging from 1140 to 1220°C and the dependence of the dielectric properties of the ceramics on the sintering condition is found to be insignificant. The relative densities of the specimens are higher than 95 % for the entire temperature range tested during the experiment. Specimen using CoZnTiO 4 sintered at 1200°C possesses a combination of dielectric properties with e r * 17.31, Q 9 f * 97,571 GHz (where f = 8.84 GHz, is the resonant frequency) and s f * -36.4 ppm/°C, which makes it a suitable candidate material for microwave devices.

AbbreviationsST = sintering temperature ( • C) r = relative permittivity , f = measurement frequency (GHz) f = coefficient of temperature variation of resonant frequency (ppm/ • C) No. = serial number Qf = quality factor frequency product (GHz)The table lists the key property data of microwave dielectric materials available from published materials. These data are the relative permittivity ( r ), the product of the Q-factor and the frequency (Qf ), the frequency of measurement (f), and the temperature coefficient of the resonant frequency ( f ). In tabulating these data, we make no judgment on the measurement method and the reliability of the result. It is known that the ceramic properties such as porosity, grain size, raw materials used, impurities, measurement methods, and equipment used for measurements affect the dielectric properties and readers should be aware that exact comparison of data on materials of identical composition and manufactured in different laboratories using different processing conditions and measured by different methods would be expected to lead to small variations in properties. The data of dielectric measurements carried out using impedance methods at low (MHz) frequency is excluded as the errors in these methods mean that a loss tangent less than 10 −3 is unreliable. The data are arranged in the order of increasing relative permittivity. The quality factor of the microwave dielectric ceramics decrease significantly with increasing relative permittivity, as shown in Figure A.1. The inset in the figure shows the variation of quality factor frequency product with Microwave Materials and Applications, First Edition. Edited by Mailadil T.
