A Study of the Series of Glasses Containing Sodium Oxide, Boric Oxide and Silica

JSGT_1934_V18_T032_T066

Nearly fifty glasses, belonging to the three series Na₂O–B₂O₃; Na₂SiO₃–B₂O₃; and NaBO₂–SiO₂ have been melted in the pure condition their general characteristics determined, and the annealing temperatures, densities, and thermal expansions systematically measured. In the majority of cases, maxima or minima occur on the physical property–composition curves. The general results have been correlated with other known data and attempts made, inconclusively, to establish a connection between these maxima or minima and the chemical constitution of the glass.
