Microstructures, Vickers hardness and dielectric properties of PbZrO3ceramics with co-additions of 0.5-5 vol% Al2O3nanoparticles have been investigated. The additive inhibited grain growth, with average grain size decreasing from ∼13 μm for PbZrO3to ∼1 μm for the nanocomposites. The mode of fracture...
