Effect of heat treatment on the grain boundary of lead titanate (PbTiO3)
Abstract
Tetragonal lead titanate ceramics in nano particles forms were fabricated via sol-gel method. The gelation was achieved via mixing a solution of lead acetate, titanium isopropoxide in a solvent system of ethanol and acetylacetone. The gel was heated in a normal air oven at 120°C for 5 hours to get ceramic powder which was calcined at 600°C for two hours and cintered upto 1100°C. The calcined powder was characterized by X-ray diffraction XRD and SEM analysis. It has been observed that the particle size increases with temperature with a decrease in grain boundary area.
