This study was carried out so as to obtain basic data on Zn–Al, Zn–Sb, Zn–Sn, Zn–Pb, Cd–Sb, Cd–Sn and Cd–Pb alloys which were heated at such high temperatures as their boiling points.<BR>First, in accordance with the illustrating method described in the previous paper, the following were illustrated and calculated for the above alloys:<BR>(1) Curves of evaporation rates W vs temperature T (over the range of about 700∼1500°K)<BR>(2) Constants B and C of evaporation rates<BR>(3) Latent heat of evaporation L₀<BR>(4) Curves of evaporation energy ε vs temperature T<BR>Next, the curves of evaporation rate W vs temperature T for the above alloys were compared with the curves converted from the vapor pressure vs temperature: curves, which had been reported by Burmeister, Kubaschewski, Schneider and others.<BR>Comparison of these two curves shows that they are in relatively good agreement over the evaporation rate less than about 20 g · cm⁻² · sec⁻¹ (the range of less than about 760 mmHg in vapor pressure). However, the above agreement held only in the range of zinc more than 20∼30 wt% for zinc binary alloys and in the range of cadmium more than 30 wt% for Cd binary alloys.
