Nb2O5-doped BaTiO3 semiconductor

Semiconducting Nb₂O₅-doped BaTiO₃ was prepared and characterized by X-ray diffraction, electron microscopy, thermogravimetry, and electrical measurements. The addition of the Nb₂O₅ donor dopant does not affect the sequence of chemical reactions during the synthesis of the ceramic material. The effect of microstructure on the semiconducting properties of barium titanate was studied. Electrically stable (Ba_1-yCa_y)(Ti_1-xNb_x)O₃ ceramics were prepared.
