“…Microwave dielectric ceramics find widespread application in microwave devices, including resonators, filters, oscillators, phase shifters, microwave capacitors, and microwave substrates. This is owing to their serialized dielectric constants, low loss, and high stability, which enable fabrication of smaller microwave integrated circuits and an increase in packaging density 1–4 . Meanwhile, the low‐temperature co‐fired ceramics (LTCCs) play a non‐negligible role in the modularity and integration of devices 5–7 .…”

“…This is owing to their serialized dielectric constants, low loss, and high stability, which enable fabrication of smaller microwave integrated circuits and an increase in packaging density. [1][2][3][4] Meanwhile, the low-temperature co-fired ceramics (LTCCs) play a non-negligible role in the modularity and integration of devices. [5][6][7] LTCCs in the millimeter wave region are characterized by the low dielectric constant, high-quality factor, and near-zero temperature coefficient of resonant frequency, which can be achieved at low sintering temperatures (below the melting point of 961 • C for silver).…”

In this study, the microwave dielectric properties of Co2+‐substituted BaZnP2O7 ceramics prepared through conventional solid‐state synthesis were investigated. X‐ray diffraction, Rietveld refinement, energy‐dispersive spectroscopy, and Raman spectroscopy all indicated that BaZn1−xCoxP2O7 ceramics sintered at 875°C were composed of a single phase. The lattice strain and crystallite size were estimated using Williamson–Hall (W–H) method. Both the scanning electron microscopy images and density measurements showed that Co2+ ions had an effect on the grain growth and densification of ceramics. The microwave dielectric properties were influenced by the intrinsic and extrinsic factors that varied with the increase of x value. An optimal performance (εr = 7.62, Q × f = 600 45 GHz, and τf = −74 ppm/°C) was achieved at x = .01. The porosity and relative density played a significant role in the dielectric constant εr: the denser the ceramic structure, the larger the dielectric constant. The Q × f and τf values were negatively correlated with the full width at half maximum of the Raman vibrational peak at approximately 1049 cm−1. Moreover, the Q × f value was improved compared to that of the undoped BaZnP2O7 ceramics. Therefore, cobalt ion substitution is an effective strategy to enhance the performance of microwave dielectric ceramics.
