This table gives the sublimation (vapor) pressure of some representative solids as a function of temperature. Entries include simple inorganic and organic substances in their solid phase below room temperature, as well as polycyclic organic compounds which show measurable sublimation pressure only at elevated temperatures. Substances are listed by molecular formula in the Hill order, with inorganic compounds preceding compounds containing carbon. Each substance has two rows of data. The top row has temperatures; the bottom row has the values of the sublimation pressure at that temperature.
Values marked by * represent the solid–liquid–gas triple point. Note that some pressure values are in pascals (Pa), and others are in kilopascals (kPa).
