N2 - A criterion for judging the nucleation form in highly undercooled liquid has, respectively, been derived from the nucleation and structure of liquid. It is found that the nucleation form of a highly undercooled liquid can be judged by determining the Sv in the liquid (where Sv is the surface area of the supposed catalyst in a unit volume of the liquid). When the determined value of Sv is equal to 1010±1 m-1, the liquid has nucleated homogeneously; it has nucleated heterogeneously if the determined value of Sv is less than 1010±1 m-1. By calculating the values of Sv in highly undercooled aluminum, copper, and silver, it is found that only silver melted under a slag has been undercooled to its undercooling of homogeneous nucleation.
