将熔融硅酸盐熔体溶液模型引入蒸发模型中，成功地再现了无碱、含FeO(大于或等于2摩尔%)的球粒陨石熔体在1700至2000℃温度下的蒸发行为。结合针对贫铁熔体的Berman CMAS熔体溶液模型，现在可以在非常广泛的条件下模拟无碱熔体的蒸发。当Al/(Na+K)和Gt；1时，基于熔体的蒸发模型也能很好地再现K的蒸发行为。但Na蒸发实验的重现性要差得多。
Incorporation of the MELTS silicate melt solution model into models of evaporation successfully reproduces the evaporation behavior of alkali-free, FeO-bearing (greater than or equal to2 mol%) chondritic melts at temperatures between 1700 and 2000 degreesC. In conjunction with the Berman CMAS melt solution model for FeO-poor melts, evaporation of alkali-free melts can now be modeled over a very wide range of conditions. MELTS-based evaporation models can also quite successfully reproduce the evaporation behavior of K when Al/(Na+K)>1. However, reproduction of Na evaporation experiments is much poorer.
