Chemical processing of lead metatitanate by co-precipitation and sol-gel methods: The role of powder and gel characteristics on crystallization behavior

This thesis reports on preparation of PbTiO$\sb3$ by two chemical methods: (i) aqueous co-precipitation and (ii) organo-metallic sol-gel processing. The effects of chemical processing conditions on material properties were determined. Particular attention was paid to the evolution of structure on heat treatment, and crystallization. Materials prepared by the two methods were amorphous in the as-prepared state, but transformed to the stable perovskite structure on heat treatment. Crystallization kinetics for the chemically prepared materials were compared with another type of amorphous PbTiO$\sb3$ prepared by rapid solidification. This comparison led to the identification of material parameters which aided in crystallization.
