Relationship between supercooling stability and solution structure in sodium acetate aqueous solution

We have observed the solution structure of the supercooled sodium acetate aqueous solution, especially for the existence of clusters and their crystallization process, by means of Scanning electron microscopy (SEM) with the freeze replica method. Microscopic internal structure of sodium acetate trihydrate crystals mainly constitutes the aggregates of 100–200 nm in diameter, which consists of the clusters of 10–20 nm in diameter. In the case of a...
