摘要：
The effect of partial fluorine substitution for oxygen on the properties of BaTiO3 has been studied using thermogravimetry, x-ray diffraction, electron microscopy, complex impedance measurements, and diffuse reflectance spectroscopy. The results indicate that partial fluorine substitution for oxygen influences the composition range of positive temperature coefficient of resistance behavior in ceramics with heterovalent substitution of lanthanum on the barium site.
