本文报道了在750~ 176 ℃温度范围内，Li~（3+）、Na~（3+）、K~（3+）及某些混合物的表面张力、密度和电导的研究结果。表面张力约为相应氯化物的两倍，密度和电导与氯化物相当。熔融碳酸盐的离子性质的检查从物理化学标准的基础上，这些属性;和电传输的机制被认为是在目前的理论概念。相对于Na ~ 2CO ~-K~ CO~-混合物，其表面张力和偏摩尔体积与理想混合物的理论值相差不大。
The present communication reports the results of an investigation of the properties of surface tension, density, and electrical conductance for molten Li~ CO3, Na~ CO3, and K~ CO3 and some mixtures in the temperature range of 750~ 176 The surface tensions are approximately twice the values for the corresponding chlorides; the densities and electrical conductance are quite comparable to those of the chlorides. The ionic nature of the molten carbonates is examined from the physicochemical criteria based on these properties; and the mechanism of electrical transport is considered in the light of current theoretical concepts. Relative to Na2CO~-K~ CO~ mixtures, the surface tensions and partial molal volumes indicate but little deviation from the predictions for thermodynamically ideal mixtures.
