Abstract
The effect of heating rate on the properties of ferroelectric lead magnesium niobate ceramics during calcining and sintering processes was reported in this investigation. Perovskite phase content, density, microstructure, and the dielectric properties of PMN ceramics with the heating rate from 2 °C/min to 30 °C/min were studied. Perovskite phase content was affected by heating rate, especially on the surface exposed to air. A slow heating rate caused more evaporation of PbO and resulted in porous ceramics with small grains. Increasing PMN content, density, and grain size with increasing heating rate made the dielectric constant increase.
