We encounter sublimation in several ways. You may already be familiar with dry ice, which is simply solid carbon dioxide. At −78.5°C (−109°F), solid carbon dioxide sublimes, changing directly from the solid phase to the gas phase. summary of firefly lane

"WebAt temperatures and pressures below those of the triple point, a phase change between the solid and gas phases can take place. For some substances, such as carbon and arsenic, sublimation is much easier than evaporation. This is because the pressure of their triple point is very high and it is difficult to obtain them as liquids. " - Gas to a solid phase change

A disorder-broadened first-order transition occurs over a finite range of temperatures where the fraction of the low-temperature equilibrium phase grows from zero to one (100%) as the temperature is lowered. This continuous variation of the coexisting fractions with temperature raised interesting possibilities.
