Influence of alkali reagents on phase formation and crystal morphology of hydrothermally derived lead titanate
The influence of three different alkali reagents, i.e. ammonium hydroxide, sodium hydroxide and potassium hydroxide, on phase formation and crystallite morphology of lead titanate prepared under mild hydrothermal conditions was investigated. The formation of three different phases of lead titanate i...
