  2. Enthalpy of sublimation - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_of_sublimation

    Enthalpy of sublimation. In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). It is equal to the cohesive energy of the solid.

  3. Titanium sublimation pump - Wikipedia

    en.wikipedia.org/wiki/Titanium_sublimation_pump

    Its construction and principle of operation is simple. It consists of a titanium filament through which a high current (typically around 40 A) is passed periodically. This current causes the filament to reach the sublimation temperature of titanium, and hence the surrounding chamber walls become coated with a thin film of clean titanium.

  4. Sublimation (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Sublimation_(phase_transition)

    Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. [ 1 ] The verb form of sublimation is sublime, or less preferably, sublimate. [ 2 ]Sublimate also refers to the product obtained by sublimation. [ 2 ][ 3 ] The point at which sublimation occurs rapidly (for further ...

  5. Dye-sublimation printing - Wikipedia

    en.wikipedia.org/wiki/Dye-sublimation_printing

    Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage.

  6. Thermal-transfer printing - Wikipedia

    en.wikipedia.org/wiki/Thermal-transfer_printing

    Thermal transfer is a popular print process particularly used for the printing of identification labels. It is the most widely used printing process in the world for the printing of high-quality barcodes. Printers like label makers can laminate the print for added durability. Thermal transfer printing was invented by SATO corporation.

  8. Dry ice - Wikipedia

    en.wikipedia.org/wiki/Dry_ice

    The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water ice and leaves no residue as it changes state. [4] Its enthalpy of sublimation is 571 kJ/kg (25.2 kJ/mol, 136.5 calorie/g). Dry ice is non-polar, with a dipole moment of zero, so attractive intermolecular van der Waals forces ...

  9. Triple point - Wikipedia

    en.wikipedia.org/wiki/Triple_point

    In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases ( gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. [ 1] It is that temperature and pressure at which the sublimation, fusion, and vaporisation curves meet. For example, the triple point of mercury occurs at ...
