It also reported to crystallize in a tetragonal unit cell with a=8.52Å and c=5.210Å leading to some possible application as hydrophone, transducer and second harmonic generation and low temperature co-fired ceramics (LTCC). B2TS2 were synthesized by conventional solid state reaction. Phase-pure B2TS2 was obtained after heating the pellets at a final sintering temperature of 1230 °C in air at 92 h. Study found that Fresnoite B2TS2 is a type of materials which are not ferroelectric and instead show perfect dielectric insulator behaviour with resistance >106Ωcm at temperatures below 750°C and also shows nonideal debye respone. The activation energy for conduction of B2TS2 samples is very high, indicating that these materials are highly insulating. 2014-05-29T07:17:40Z 2014-05-29T07:17:40Z 2013 Article Advanced Materials Research, vol. 795, 2013, pages 640-643 978-303785811-0 1022-6680 http://www.scientific.net/AMR.795.640 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34866 en Trans Tech Publications |
