Ceramic composites with nanoparticles are intensively investigated due to their unique thermal, mechanic and electromagnetic properties. In this work, dielectric properties of phosphate ceramics with round silver nanoparticles of various sizes were studied in the wide frequency range of 20 Hz-40 GHz for microwave shielding applications. The percolation threshold in ceramics is close to 30 wt.

- Researchers created composite materials with high levels of a specific ferroelectric compound (0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3) mixed into phosphate-bonded ceramics under varying pressures.
- All samples displayed a consistent distribution of the active ferroelectric phase and maintained thermal stability up to 900 K.
- The study found that the density of these composites varies in a non-linear way with pressure, with increased density leading to higher dielectric permittivity and strong piezoelectric properties.
