Correction: Effect of AlF₃ on the Density and Elastic Properties of Zinc Tellurite Glass Systems. Materials 2012, 5, 1361-1372.

Due to an oversight, the data of the last column “Vs” in Table 1 was missing in the original version of this article [1].

Table 1. Glass composition, density, molar volume, molecular weight, longitudinal and shear ultrasonic wave velocities of (AlF₃)_x-(ZnO)_y-(TeO₂)_z glasses. The pure TeO₂ glass is included for comparison.
