Effects of excess PbO on the preparation process of modified lead–calcium titanate ceramics

Microelectronic Engineering, 2003
The effects of excess PbO on the preparation process of modified lead-calcium titanate ceramics were studied. The sintering period were divided into two stages: the initial sintering stage and the grain growth stage, at which the temperatures were chosen to be 980 and 1000 °C, respectively.

Effect of excess PbO on microstructure and orientation of PZT(60/40) films

Journal of Electroceramics, 2009
Lead zirconate titanate [PZT(60/40)] films were deposited by RF-magnetron sputtering using single oxide targets with various levels of excess PbO. The excess PbO in the film played an important role in the pyrochlore-to-perovskite transformation, nucleation and growth processes, orientation control, and crack formation.

Dielectric properties due to excess PbO and MgO in lead magnesium niobate ceramics

Ferroelectrics, 1988
Abstract The dielectric properties of lead magnesium niobate (PMN) have been investigated as a function of the amount of excess PbO and excess MgO in the range of 0–40 m/o and 0–150 m/o, respectively. In the case of PMN with both 40 m/o excess PbO and 5 m/o excess MgO added, the pyrochlore phase was completely eliminated.

Effect of PbO excess on sintering and piezoelectric properties of 12Pb(Ni1/3Sb2/3)O3–40PbZrO3–48PbTiO3 ceramics

Materials Chemistry and Physics, 2003
Abstract The effect of PbO excess on the sintering and piezoelectric properties of 12Pb(Ni1/3Sb2/3)O3–40PbZrO3–48PbTiO3 ceramics has been investigated on specimens produced from PbO, TiO2, ZrO2, NiO, and Sb2O3 powders as starting materials. When the PbO excess content was below 3.0 wt.% and the mixture of starting materials calcined at 850 °C for 2 h,

Low-temperature sintering of 12Pb(Ni1/3Sb2/3)O3–40PbZrO3–48PbTiO3 with V2O5 and excess PbO additives

Journal of the European Ceramic Society, 2002
Abstract Low-temperature sintering of 12Pb(Ni 1/3 Sb 2/3 )O 3 –40PbZrO 3 –48PbTiO 3 (12PNS–40PZ–48PT) calcined powders with V 2 O 5 and excess PbO additives has been investigated. Adding 0.20 to 0.40 wt.% V 2 O 5 and 1.0 wt.% excess PbO to 12PNS–40PZ–48PT calcined powders and sintering at 950 °C for 4 h, the sintered samples only contain the ...

Effect of excess PbO on microstructure and electrical properties of PLZT7/60/40 ceramics derived from a high-energy ball milling process

Journal of Alloys and Compounds, 2002
Abstract A high-energy ball milling process has been used to prepare lead lanthanum zirconate titanate (PLZT7/60/40) powders with different excess PbO levels. The microstructure development and the electrical properties of the PLZT ceramics derived from the synthesized powders were investigated.
