“…However, most high Q × f dielectric materials are manufactured at high sintering temperatures, which hinder their incorporation with low melting-point electrodes and polymer-based substrates and lead to excess energy consumption and evaporation of volatile components. For practical application, LTCC requires excellent microwave dielectric properties, low sintering temperature, and adequate co-fire matching between ceramics and electrodes [5][6][7][8][9][10]. Materials with low melting points are often added to LTCC to reduce the required firing temperatures.…”

This study investigates the bulk density, sintering behaviour, and microwave dielectric properties of the MgO-2B2O3 series ceramics synthesised by solid-state reaction. According to the X-ray diffraction and microstructural analyses, the as-prepared MgO-2B2O3 ceramics possess a single-phase structure with a rod-like morphology. The effects of different quantities of H3BO3 and BaCu(B2O5) (BCB) on the bulk density, sintering behaviour, and microwave dielectric properties of the MgO-2B2O3 ceramics were investigated. Accordingly, the optimal sintering temperature was obtained by adding 30 wt% H3BO3 and 8 wt% BCB. We also reduced the sintering temperature to 825 °C. Furthermore, the addition of 40 wt% H3BO3 and 4 wt% BCB increased the quality factor, permittivity, and temperature coefficient of resonance frequency of MgO-2B2O3 to 44,306 GHz (at 15 GHz), 5.1, and −32 ppm/°C, respectively. These properties make MgO-2B2O3 a viable low-temperature co-fired ceramic with broad applications in microwave dielectrics.

“…High sintering temperatures not only hinder their incorporation with low melting electrode and polymer based substrates but also lead to huge energy consumption and volatile components evaporation. For practical application, LTCC requires not only excellent microwave dielectric properties but also low sintering temperature and good co-fire matching between ceramics and electrodes [5][6][7][8][9][10]. Materials with low melting point are often added in order to lower the firing temperatures.…”

The bulk density, sintering behavior and microwave dielectric properties of MgO-2B2O3 series ceramics synthesized by solid-state reaction method were systematically studied in this paper. X-ray diffraction and microstructural analysis revealed that the as-prepared MgO-2B2O3 ceramics possessed a single-phase structure with rod-like morphology. Through the investigation of the effects of different dosages of H3BO3 and BCB on bulk density, sintering behavior and microwave dielectric properties of MgO-2B2O3 ceramics, the optimum sintering temperature was obtained at an addition of 30wt%H3BO3 and 8wt%BCB and the sintering temperature was reduced to 825 oC. The addition of 40wt %H3BO3 and 4 wt%BCB increased the quality factor Q×f, permittivity εr and temperature coefficient of resonance frequency τf of MgO-2B2O3 to 44,306 GHz, 5.1 and -32 ppm/oC, respectively, meeting the criteria of low-temperature co-fired ceramics.

“…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.
