Abstract

This paper studies the effect of Mo as a reducing additive on the degree of oxidation of the coloring agent and also of the action of the latter on the electrodes for its theoretical and practical importance. The authors melted the glasses in crucibles with an addition to the batch of 0.4% Mo metal chips to 100 kg of glass. At the same time they melted glasses without the addition of Mo. An analysis of the spectral curves of glasses colored by Mn, Cr, or Ce compounds in combination with Ti, showed that in the presence of Mo there is a significant change in the intensity of color and a shift in the transmission maxima. When Mo is used in industrial conditions it is necessary to adjust the composition of the batch; to change the concentration of coloring agent and to add auxiliary materials (oxidizers, finers, etc.).
