摘要: We present a facile sol–gel route to synthesize lanthanum-substituted bismuth titanate (BLT). The chemical reactions and crystallization process of this method using the initial materials subnitrate [4BiNO3(OH)2·BiO(OH)], lanthanum nitrate [La(NO3)3·6H2O] tetrabutyl [Ti(C4H9O)4] were investigated by thermogravimetric differential thermal analysis, IR spectroscopy, gas chromatography/mass spectrometry, Raman spectroscopy XRD. evaporation dissolved CO2 in amorphous BLT matrix is associated with BLT. gel pure perovskite when calcination temperature higher than 500 °C. grain size obtained nanoparticles ranges from 15 82 nm. Arrhenius curve representation reduced sizes respect temperature. activation energy growth 0.36 eV, which shows rapidly range 500–850
