钠、钾和铵的酸性硫酸盐的许多物理化学性质已经与解释它们的低熔点和阐明固体和熔体的结构特征的目的相关联。结果表明,熔体是离子型的,低熔点与两种效应有关:(i)大的熔化熵(约为1.25)。23口径/ mole deg.); (ii)在固体中形成裂纹的活化能相对较低。
A number of physico-chemical properties of the acid sulphates of sodium, potassium and ammonium have been correlated with the object of interpreting their low melting points and elucidating structural characteristics of solids and melts. It has been shown that the melts are ionic and that the low meltingpoints are associated with two effects:(i) a large entropy of fusion (approx. 23 cal./mole deg.);(ii) a comparatively low activation energy of flaw formation in the solid.
