Titanium‐containing glasses were prepared by fusion of a base glass (BaO·B 2 O 3 SiO 2 ) and TiO 2 and/or Ti 2 O 3 in Ar. Their resistivities did not vary with melting time and temperature. Interaction of Ti 4+ and Ti 3+ in the glasses was deduced by spectroscopy, but the valence states in the batch compositions were preserved in the glasses, according to the chemical analysis. Glasses containing either Ti 4+ or Ti 3+ had very high resistivities, whereas the glass prepared by melting a mixture of a Ti 4+ ‐containing and a Ti 3+ ‐containing glass had much lower resistivity. All results confirmed the possibility of controlling the resistivity by batch composition for these glasses.
