摘要

In this paper, xLi 2 O-yK 2 O-(1-x-y)Nb 2 O 5 , x = 0 - 1 and y = 0 - 1, system was partially studied using Lithium and Potassium Niobate as sintering materials in order to reduce the sintering temperature. The prepared lithium potassium niobate ceramics are characterized using X-ray diffraction method and grain size have been calculated using SEM photographs; the phase transitions have been observed from DSC experiment. Finally, the piezoelectric and dielectric characteristics of these mixed ceramic systems are also investigated. The planar mode electromechanical coupling coefficient k p reaches 33.5% and two phase transitions (orthorhombic - tetragonal; tetragonal - cubic) have been observed.
