摘要
Nano-sized PbTiO3 powders have been successfully synthesized using the high energy ball milling technique. The materials used are PbO and TiO2 Anatase and Rutile powders. The powders milled for different hours are characterized using XRD and TEM. Experimental results show that the single perovskite phase of PbTiO3 can be readily formed by the high energy ball milling process without any post-annealing, indicating that nano-sized PbTiO3 can be obtained using a simple, low-cost, room temperature processing technique which is free of volatility of lead. The relationship between the microstructure of the synthesized PbTiO3 powders and milling hours is also discussed.
