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

Elucidating the microwave dielectric properties of (Mg(1−x)Znx)2SnO4 ceramics

“…These enable small devices with low loss and high temperature stability, respectively, to be fabricated [1,2]. However, the carrier frequencies of interest are from the ISM (industrial, scientific and medical) bands to values that correspond to millimeter wavelengths.…”

Low-temperature sintered Zn2SiO4–CaTiO3 ceramics with near-zero temperature coefficient of resonant frequency

“…There are three methods to reduce the sintering temperature of microwave dielectric ceramics: first, low melting oxide, mixture oxide or glass addition; second, chemical processing; and finally the use of smaller particles as the starting materials [11][12][13][14][15][16][17][18][19][20][21]. The chemical method is time-consuming and expensive.…”

Dielectric properties and crystal structure of Mg2TiO4 ceramics substituting Mg2+ with Zn2+ and Co2+

“…The unique electrical properties of ceramic dielectric resonators have revolutionized the microwave-based wireless communications industry by reducing the size and cost of filter and oscillator components in circuit systems [3][4][5][6]. At the same time, in order to work with high efficiency and stability, many researches have been focusing on developing new dielectric materials with a high quality factor (Q × f) and a near-zero temperature coefficient of resonant frequency ( f ) for use as dielectric resonator and microwave device substrate [7][8][9].…”
