- Sublimation - This term refers to the phenomenon where a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase. Conversely, it also refers to the phenomenon of transitioning from the gas phase to the solid phase, but these are generally referred to as deposition, solidification, or recrystallization. - Conditions for the Occurrence of Sublimation - Common substances exhibit three states: solid, liquid, and gas, which are determined by temperature changes. The boundary temperatures are defined by the "vapor pressure" of each substance. Since the phase change temperature is dictated by vapor pressure, by altering the environmental conditions (reducing pressure), sublimation can occur in many substances without passing through the liquid phase. - Applications of Sublimation and Sublimation Purification Devices - Many compounds have their own specific sublimation and solidification temperatures. By utilizing this temperature difference, it is possible to significantly separate mixed compounds. This phenomenon is applied in sublimation purification devices. Taking advantage of the property that allows direct phase transition from solid to gas, it is widely used for the high purification of "insoluble" substances that are difficult to dissolve in solvents.
