Sintering behavior, crystal structure, and microwave dielectric properties of a novel NaY9Si6O26 ceramic

“…26 Figure 4A shows the relative density and ε r curves for NaY 9 Si 6 O 26 ceramics sintered at varying temperatures. The highest relative density, reaching 96.5%, was achieved at a sintering temperature of 1465 • C, closely approaching the theoretical density of 4.58 g/cm 3 . Conversely, inadequate sintering is evident at 1415 • C, resulting in a relative density of only 92.7%.…”

“…1,2 Notably, the pursuit of microwave dielectric ceramics possessing specific attributes such as an optimal relative dielectric constant (ε r ), a high-quality factor (Q × f), and a near-zero temperature coefficient of resonant frequency (τ f ) has gained paramount significance. [3][4][5][6] A lower relative dielectric constant holds the promise of reducing signal transmission delays, thereby mitigating heat generation within the system. This, in turn, facilitates the use of microwave ceramics with lower relative dielectric constants in high-speed communication equipment.…”
