Abstract

Nanocomposites of 0.96(0.91Pb(Mg_1/3Nb_2/3)O ₃-0.09PbTiO₃)-0.04BaTiO₃ (PBT) with Ag were prepared via synthesis of low-temperature-sinterable PBT/Ag composite powder and its surface modification with a MgO sol. Dielectric properties and modulus of rupture were investigated as a function of the amount of the MgO sol at sintering temperature in the range from 850 to 1000°C. The MgO sol seemed to suppress the diffusion and migration of Ag during the heat treatment to give rise to the homogeneous microstructure with 300-80 nm of Ag particles in about 3.5-2.5 μm grains. The proper amount of the MgO sol seemed to be 0.5-1.0 wt.% for the PBT powder with 3.0 mol% Ag. The PBT/Ag nanocomposites showed density >99% T.D., ε_rt of 18,000-20,000, tan δ of 1-0.5%, specific resistivity of 10¹² Ω cm, and MOR of 125-145 MPa.
