A variety of new ternary arsenate glasses formed from mixtures of ionic alkali‐metal meta‐arsenates (MAsO 3 ) with somewhat covalent higher valence metal oxides (MO x ) have been prepared. From rate‐of‐hydrolysis comparisons, it has been found that bonding in these glasses is enhanced by de‐protonization. The latter is enhanced through processing using alkali‐metal flourides and increases the number of direct oxygen links between the higher valence metals. Stabilization also tends to increase with the covalent bonding or chain‐forming character of the latter metals as well as with the electrostatic binding between alkali‐metal ions and the chain linkage oxygens.
