The Influence of Different Elements on the Colour and Magnetic Susceptibility of Glass. Part II. Titanium and Chromium

JSGT 1954 V38 T084-T088

The influence of titanium and chromium ions on the transmission of some glasses in the ultra-violet has been studied. It appears that the influence of chromium ions on the transmission of glass in the ultra-violet is negligible. The influence of traces of titanium on the transmission of glass in the ultra-violet seems to depend largely on the valency state of the titanium ions. This was confirmed by measurements on the magnetic susceptibility of titanium-containing glasses. Most probably titanium ions are surrounded by four oxygens in glass.
