Summary

The authors have been studying a suspension (slush ice) made from an oil-water mixture by cooling and stirring. From the study results, it was found that an additive having both an amino group (NH2) and a silanol group (SiOH) was essential to form a suspension with high IPF without adhesion of ice to the cooling wall. Moreover, ice particles formed in the suspension were dispersed and granular, and did not stick to each other. In this paper, the authors carried out experiments to clarify the characteristics of the suspension formation process. From a thermal analysis of the substance formed in the suspension by difference scanning calorimeter, it was found that the substance was not ice but a compound of ice and additive. Then, at a very small depression of freezing point (about 7 °C) all water in the mixture could be frozen by using the additive.
