用变颈法研究熔盐的密度和表面张力

Study of Density and Surface Tension of Molten Salt by Using Differential Neck Method

摘要: 用变颈法对KC1-NaC1熔盐体系的密度和表面张力进行了测定.为简化计算,对原式作了变换,密度的测量结果与公认值非常接近;因缺乏精确的接触角数据,故合理地假定接触角等于零(即θ=0),因此只得到表面张力的估算值.

Abstract: Density and surface tension of molten binary salt KCI-NaCl system has been mesured by using a new method-Differential Neck Method.The results of measurement of density agree with the accepted values very well.The results of measurement of surface tension is estimated,assuming the contact angle is equal to zero(i.e θ=0).
