Compositions, Physical and Chemical Properties, and Compatibility of Lead–Boron–Silicate Glass with Ruthenium(IV) Oxide Compounds

Abstract—The information on the compatibility of lead–boron–silicate glass of various compositions and ruthenium(IV) oxide compounds is systematized. The chemical processes occurring between them are established in terms of the theory of the acid-base interaction. The informative indicators that determine the direction of such interaction are the acidity, ionic potential, or orbital electronegativity of the components included in the composite materials. The established regularities can be used for selecting the composition of lead- and cadmium-free glass in the development of advanced ruthenium resistors and ruthenium-containing materials.
