ABSTRACT:
The present invention concerns sodium silicate and sodium aluminosilicate glass compositions which contain specified proportions of tantalum oxide and glass electrodes made therefrom, which are particularly sensitive to sodium ions in aqueous solutions containing sodium ions and other monovalent cations. These glasses represent an improvement over sodium aluminosilicate glass electrodes of the type disclosed in U.S. Pat. No. 2,829,090.
