Influence of Electrohydropulse on Sb Doped Ba0.95Pb0.05TiO3 Phase

Popis výsledku v původním jazyce

Sb doped Ba0.95Pb0.05TiO3 phase (BPT) was prepared by mechanical milling powder precursors and following, the calcination of homogeneous mixture at 1050.DEG.C. Electrohydropulse (EHP) refining BPT phase was done at two different energies of 3.3x10 4 and5x10 4 J/m for 3 and 4 minutes in technical water. The magnitude of specific surface has been increased from 2.3 m2/g in the starting calcinate to 4.4 m2/g in the sample treated at the highest energy for 4 minutes. The primary product of the interactionof electric discharge with the surface of BPT phase in water environment was Ba(OH)2, which absorbs air CO2 and coats the surface of EHP treated BPT particles by a BaCO3 layer. The cubic phase on the surface of powder particles of original BPT phase wasalmost completely removed by the EHP treatment. The microstructure of ceramics was not influenced by the EHP treatment of calcinates.
