Abstract
IN a previous communication1, it was shown by us that alkali halides such as lithium, sodium, potassium, rubidium and cæsium chloride dissolved in fused boric oxide giving a homogeneous glass. X-ray examination of these glasses reveals sharp diffraction lines due to the dissolved alkali halides together with a few foreign lines which cannot be identified with any known borates of the metals. These foreign lines are largely present in glasses containing chlorides of alkali metals of low atomic numbers, but are absent with rubidium and cæsium halides. It was found later that these foreign lines are due to a variety of anhydrous crystalline B2O3, first studied by Cole and Taylor2, in the case of boric oxide glasses, and to anhydrous Na2B4O7 in the case of borax glasses.
