(1-x)Bi(Sc1-yYy)O3-xPbTiO3 (BSYPTx/y) ceramics were prepared by the conventional mixed oxide method. It was found that the morphotropic phase boundary (MPB) between rhombohedral and tetragonal phase of BSYPTx/y system was moved to the lower PT content with increasing of BiYO3 content. The Curie temperature (TC) near MPB of BSYPTx/y ceramics was found to increase with increasing of BiYO3 content. However,...
Novel perovskite (1-x)BiInO3-xPbTiO3 (BIPT) ceramics with high Curie temperature were prepared by conventional oxide process. The experiment results show that it was difficult to synthesize BIPT ceramics with the stable perovskite phase unless the content of PbTiO3 is more than 75%. Moreover, the morphotropic phase boundary (MPB) composition of BIPT has been predicted in the range of x=0.85-0.95....
-The ternary system of yBiGaO3-(1-x-y) BiScO3-xPbTiO3 (BGS-PT) ceramics was prepared by using conventional mixing oxide process. X-ray diffraction analysis reveals that BGS-PT ceramics show the perovskite structure. The Curie temperature of BGS-PT ceramics was found to be increased with increasing of BiGaO3 content. However, more BiGaO3 content would lead to sharply decreased piezoelectric properties...
The ternary system of j/BiGaO3-(1-x-y) BiScO3-xPbTiO3 (BGS-PT) ceramics was prepared by using conventional mixing oxide processing. X-ray diffraction analysis revealed that the BGS-PT ceramics showed the perovskite structure. The Curie temperature (TC) of BGS-PT ceramics was found to increase with increasing BiGaO3 content. However, a larger BiGaO3 content led to sharply decreased piezoelectric properties,...
