含铁闪锌矿热容与其FeS含量的关系

Relationship Between the Heat Capacity and the Content of FeS in Fe rich Sphalerite

本文在利用ＤｕＰｏｎｔ公司的９９００型差式扫描量热仪（９９００ＤｉｆｅｒｅｎｔｉａｌＳｃａｎｎｉｎｇＣａｌｏｒｉｍｅｔｅｒ，简称ＤＳＣ）对７个含铁闪锌矿样品的定压摩尔热容量进行实验测定的基础上，分析了热容与ＦｅＳ含量的关系。１样品特点及实验结果７个含...

According to the thermodynamic laws, the heat capacities (C p·m ) of (Zn 1 x ,Fe x )S had been measured by the DuPont differential scanning calorimeter(DSC). The experimertal results showed that the C p·m was related to the thermodynamic properties and the contents of FeS in (Zn 1 x ,Fe x )S.The relationship was represented by the following equations( C p·m in J·mol -1 ·K -1 ): 400K: C p =48 99-0 90 X +6 95×10 -2 X 2-1 84×10 -3 X 3 500K: C p =50 11-1 44 X +0 13 X 2-4 12×10 -3 X 3 600K: C p =48 89-1 62 X +0 13 X 2-4 37×10 -3 X 3 700K: C p =48 07-2 24 X +9 17×10 -2 X 2-1 21×10 3 X 3 800K: C p =47 12-3 19 X +0 27 X 2-7 48×10 3 X 3 The data about the themodynamic properties of (Zn 1- x ,Fe x )S obtained from this paper were very useful to the systematic researches on sphalerite and physic chemical condition for its mineralization.
