摘要：

In this paper solid solutions in the GaxTi1-2xNbxO2 system have been synthesized and characterized by X-ray diffraction, UV-visible spectroscopy, Infrared spectroscopy and electronic microscopy. Measurements of unit cell parameters and interatomic distances allow two kinds of solid solutions to be considered, one based on the rutile structure when the TiO2 amount is high and the other on the orthorhombic alpha-PbO2 structure when the TiO2 content is low. The range of solid solution formation has also been established in the two kinds of solid solutions, x less-than-or-equal-to 0.3 for the former and 0.38 less-than-or-equal-to x less-than-or-equal-to 0.45 for the later.
