Sol-gel-derived PbTiO3

Journal of Materials Science, 1985
The sol-gel process is a technique which is applicable for forming ceramic materials. In this process, liquid precursor materials are reacted to form a sol which then polymerizes into an inorganic polymeric gel. Advantages of this process over standard powder preparation of ceramics are: purity, homogeneity, control of macro- and micro-structures, and ...

Impact of alternating current electric field poling on piezoelectric and dielectric properties of Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 ferroelectric crystals

Journal of Applied Physics, 2020
Compared with the state-of-the-art Pb(Zr,Ti)O3 ceramics, relaxor-PbTiO3 (PT) based ferroelectric single crystals possess much higher piezoelectricity, thus receiving considerable attention from the ferroelectric community. Recently, it was found that the

Ferroelectric properties of PbTiO3

Physica, 1962
Abstract A new method for growing single crystals of ferroelectric PbTiO3 is described. A mixture of TiO2, Pb3O4 and KF in the ratio 1 : 2.5 : 6.5 is taken in a platinum crucible and heated to a temperature of about 900°C to 950°C for about 20 hours. The melt is then slowly cooled to room temperature.

Negative‐Pressure‐Induced Large Polarization in Nanosized PbTiO3

Advances in Materials, 2020
Ferroelectric materials usually undergo decay with particle size decreasing into the nanoscale. At the critical value, the crystal structure undergoes a transition from the ferroelectric to paraelectric phase and the ferroelectricity vanishes.
