L. Perez-arrieta et al., Synthesis, structural, and morphological characterization of ceramics in the system Bi2O3-TiO2-CuO, J MATER RES, 14(3), 1999, pp. 824-828
This paper reports the formation of a solid solution in the system Bi2O3-Ti
O2-CuO. This solid solution seems to be isostructural with Bi4Ti3O12, accor
ding with the x-ray powder diffraction patterns. Microstructural studies do
ne using scanning electron microscopy show the typical elongated Bi4Ti3O12
grain morphology only in samples with 2 : 2 : y molar ratios of the Bi2O3 :
TiO2 : CuO oxides (y = 1, 2, or 3).
