Original Paper


In order to achieve detached solidification under gravity conditions, we conduct a series of experiments by using the water which is filled with CO2 gas and the oil whose solidification temperature is higher than water. When the tube (conical flask) is moved by the translation controller from hot region to cold region, the CO2 bubbles overflow from the water to the interspace between the oil and the tube wall due to the different solubility of CO2 in water and ice. At the same time, the oil upon the water begins to solidify and prevents the CO2 bubbles from escaping from the interspace. As a result, detached solidification is successfully achieved because of the appearance of a gas gap filled with CO2 between the oil and the tube wall. The experimental results show: (1) the conical flask is a good apparatus to achieve a gas gap between the oil and the tube wall; (2) the optimal temperature of the cold bath is about −10 °C, and the result of detached solidification is better when the temperature of the cold bath is close to it.
