The Physical Properties of Glasses.   Part IV. The Density of Phosphate and Germanate Glasses

JSGT 1946 V30 T192-T197

The theory given in earlier communications about the density of silicate, borate and related glasses as a function of their composition is found to hold satisfactorily also for phosphate and germanate glasses. Several confirmations of the C.D. Rules 1 and 2 (cf. Paper III of this series) are given. A survey of the χ values for the different glass-formers estimated hitherto is given, and their relations to .other physical quantities are discussed.
