Sodium molybdate‐hexagonal boron nitride composites enabled by cold sintering for microwave dielectric substrates

To fulfill the demands of more bandwidth in 5G and 6G communication technology, new dielectric substrates that can be co-fired into packages devices have low loss improved thermal conductivity are desired. The motivation for this study is to design composites with (tan δ) high (κ), while still limiting electrical conductivity, microwave applications involving power frequency. This work describes fabrication high-density electroceramic a model material cold sintering, namely sodium molybdate (Na2Mo2O7), fillers higher such as hexagonal boron nitride. physical properties were characterized function filler vol.%, temperature, Understanding variation measured achieved through analyzing respective transport mechanisms.
