Dielectric Properties and Applications of Low‐Loss (1−x)(Mg0.95Ni0.05)2TiO4‐xSrTiO3 Ceramic System at Microwave Frequency

“…Research for new materials with such an optimum combination has been ongoing and reported in these few years. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Microwave dielectric properties of binary titanate ceramic Mg 2 TiO 4 has a spinel-type structure, belonging to the cubic space group Fd-3m (2 2 7). It exhibits a high dielectric constant e r $ 14, a high-quality factor Q9f $ 150,000 (GHz), and a temperature coefficient of resonant frequency s f $ À50 ppm/°C.…”

Low temperature sintering and microwave dielectric properties of (Mg0.7Zn0.3)0.95Co0.05TiO3 ceramics with BaCu(B2O5) additions

“…E-mail address: cubnck@yahoo.com.tw [6][7][8][9]. Since the ionic radius of Zn 2+ (0.083 nm) is similar to that of Mg 2+ (0.078 nm), Mg 2+ ions can be substituted by Zn 2+ ions to form (Mg, Zn)TiO 3 compositions.…”

Characterization and dielectric behavior of V2O5-doped 0.9Mg0.95Co0.05TiO3–0.1Ca0.6La0.8/3TiO3 ceramic system at microwave frequency

“…The advantage of using dielectric resonator is that it makes the size reduction of microwave components possible. Requirements for these dielectric devices must be combined with a high dielectric constant (ε r > 15) for possible size miniaturization (size of a dielectric resonator is .1/ √ ε r ), a low dielectric loss (Q > 5000, where Q = 1/tan ı) for high frequency selectivity and low signal attenuation, and a near-zero temperature coefficient of resonant frequency ( f ) for temperature stable circuits [1][2][3][4][5]. These three parameters are correlated to the size, frequency selectivity and temperature stability of the system, respectively.…”
