Synthesis and growth mechanism of donut-like lead titanate particles by hydrothermal method

The Effect of Fuel Content on the Characteristic of Lead Titanate Fine Powders Prepared by Sol-gel Combustion Method

“…Because of it shows high Curie temperature, high pyroelectric coefficient and high spontaneous polarization. Many researchers have been focused on the processing of PT powders via several methods, such as the solid-state reaction [1], sol-gel synthesis [4,5], hydrothermal reaction [3,[6][7][8], co-precipitation [9], oxidant peroxide method [10], molten salt preparation [11], polymeric precursor method [12], mechanochemical synthesis [2,13], emulsion process [14]. However, conventional solid-state reaction for preparing PbTiO 3 powders requires high calcinations temperature, which induces sintering and aggregation in the particles.…”

Relative low-temperature synthesis of lead titanate (PbTiO 3 ) whiskers via flux method

“…Traditionally, PbTiO 3 was prepared by hydrothermal (solvothermal) and sol-gel methods to obtain the precursors and then calcined at certain temperature ranges [12][13][14][15][16]. However, almost all these wet-chemistry routes required the precursors to be calcined in the temperature range of 600-1500°C, although these products have controlled morphology and stoichiometry, yet this procedure was not easy to obtain the heat resisting materials and the large particles may limit their applications in electronic devices.…”
