GROWTH AND DIELECTRIC PROPERTIES OF 0.48 Pb(Fe1/2Nb1/2)O3-0.52 PbTiO3 SINGLE CRYSTAL

GROWTH AND DIELECTRIC PROPERTIES OF 0.48 Pb(Fe1/2Nb1/2)O3-0.52 PbTiO3 SINGLE CRYSTAL

Large ferroelectric single crystals of 0.48 Pb(Fe1/2Nb1/2)O3-0.52 PbTiO3 solid solution system were first grown using a modified Bridgman technique and their properties were investigated. The obtained crystals were about 25 mm in diameter, 100 mm in length and black in color. The crystal exhibited a...

Zusammenfassung:Large ferroelectric single crystals of 0.48 Pb(Fe1/2Nb1/2)O3-0.52 PbTiO3 solid solution system were first grown using a modified Bridgman technique and their properties were investigated. The obtained crystals were about 25 mm in diameter, 100 mm in length and black in color. The crystal exhibited abnormal dielectric properties that the dielectric constant was as high as 30000 and the dielectric loss factor was about 0.5 at RT. The mechanism of this phenomenon was discussed. 13 refs.
