This paper is one of a series of investigations concerned with various physical properties of fused salts and simple glasses. The densities of liquids in the system NaCl-KCl, LiCl-KBr, NaCl-NaBr, Li_2O-B_2O_3 and PbO-B_2O_3 were measured by a counterbalanced-sphere method at temperatures ranging approximately from 800 to 1000℃. The apparatus are shown diagrammatically in Fig.1 and Fig.2. The results of the measurements are shown in Fig.3~Fig.5. From the density data the apparent mole volume of the liquids was calculated. Fig. 3~Fig. 5. From the density data the apparent mole volume of the liquids was calculated. Fig. 8 and Fig.9 illustrate the effect of Li_2O and PbO addition on the mole volume of melts. From these curves it is found that the additions of lithium and lead to B_2O_3 result in a marked contraction in the volume of mole.
