H. Idrissi et al., Molten salt prepared lead titanate: Powder characterization, sintering andphysical properties, J EUR CERAM, 19(11), 1999, pp. 1997-2004
Two tetragonal lead titanate powders, prepared by reaction in molten alkali
-metal nitrites, are differentiated by their content in sodium. The role of
sodium on the crystal lattice, sintering behaviour and physical properties
is discussed. Microstructure and ferroelectric wall domains are shown. Cur
ie temperature is determined from internal friction technique; permittivity
and electrical losses are estimated from dielectric measurements. (C) 1999
