用變頸法研究熔鹽的密度和表面張力

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

摘要: 用變頸法對KC1-NaC1熔鹽體系的密度和表面張力進行了測定.為簡化計算,對原式作了變換,密度的測量結果與公認值非常接近;因缺乏精確的接觸角數據,故合理地假定接觸角等于零(即θ=0),因此只得到表面張力的估算值.

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).
