“…In this investigation, we focused on use of pre-calcined Zn 3 B 2 O 6 zinc borate as an aid for sintering of zinc silicate. The difficulties of using B 2 O 3 in tape casting 22 and the need for the highest crystallinity for good dielectric properties are reasons for not using this material in the raw or glassy forms. The Zn 2 SiO 4 ceramic was selected because of its low dielectric constant and high quality factor.…”

The physical and dielectric properties of composites of known microwave materials, Zn 2 SiO 4 and Zn 3 B 2 O 6 , prepared by solid-state reaction, were investigated with the purpose of developing a low-loss dielectric material for low-temperature co-fired ceramic applications. An off-stoichiometric phase of Zn 2 SiO 4 with extra SiO 2 was used to avoid the occurrence of unreacted ZnO. During sintering, zinc borate was found to partially react with residual SiO 2 to form Zn 2 SiO 4 . The residual zinc borate was converted to a boron-rich glassy phase which helped to reduce the sintering temperature of the composite. Good relative sintering density (>90%) at temperatures below the melting temperature of zinc borate is indicative of a sintering mechanism of diffusion-based mass transfer. Composites containing 15 wt.% zinc borate, 2.5 wt.% lithium carbonate and 20 wt.% zinc borate in zinc silicate had dielectric constants of 6.8 and 6.1, quality factors (Q9f) of 48,800 and 94,300 GHz when sintered at 900°C and 950°C, respectively. These quality factor results are close to the best values reported for zinc silicate at these sintering temperatures.

“…George and Sebastian reported that the lithium magnesium zinc borosilicate (LMZBS) glass-doped Li 2 MgTi 3 O 8 ceramic were sintered at 925 C, and showed good microwave dielectric properties [27]. Chen reported that 0.5 wt.% of BaCu(B 2 O 5 ) modified Li 2 MgTi 3 O 8 ceramic sintered at 900 C also exhibited good microwave dielectric properties [31].…”

“…Modern electronic devices tend to be miniature and portable, thus it requires the related electronic components to be highly integrative and with high performance. To meet the requirement of the miniaturization of microwave components for wireless communication, low-temperature co-fired ceramic (LTCC) technology becomes an important method [3][4][5][6][7][8]. The dielectric material used in LTCC must have a variety of dielectric constant materials to permit future integration and embedded passive components.…”

A series of dense ceramic samples in the (1 -x)BiVO 4 -xLi 0.5 Re 0.5 WO 4 (Re = La, Nd; 0.05 B xB 0.11) has been prepared by using the traditional solid state reaction method. A single solid solution phase with monoclinic structure is formed through the entire compositions and the unit cell volume increases linearly with x. When x = 0.09, the composition of 0.91BiVO 4 -0.09 Li 0.5 La 0.5 WO 4 readily sintered at 750°C shows good microwave properties with e r of 76.7, Q 9 f of 6789 GHz and s f of 7.3 ppm/°C. As x = 0.08, the 0.92BiVO 4 -0.08Li 0.5 Nd 0.5 WO 4 ceramic sintered at 750°C possesses excellent microwave dielectric properties of e r = 71.8, Q 9 f = 7482 GHz and s f = 0.8 ppm/°C. These ceramics have applications for microwave devices requiring high permittivity and ultra-low sintering temperature.
