The release of juvenile gases and water to the surface from a magma source.
The release of gas from cooling molten rock or the interior of the Earth. Much of the atmosphere's gaseous constituents, like water vapor, nitrogen, and argon, came from outgassing.
Outgassing is a problem encountered in high-vacuum environments and applications. For example, NASA maintains a list of low-outgassing materials to be used for spacecraft, as outgassing can cause deposits on optical elements, thermal radiators, or solar cells. Materials not normally considered absorbent can release enough light molecules to interfere with industrial or scientific processes.
the escape of free gasses (ie. Carbon dioxide or oxygen) from the surface of the water.
The release of gases dissolved in hot, molten rock.
The release of a gas from some material (for example, filter media)
Venting of volatile gases from the heated interior of a solid body.
Emission of gas or air from a printed circuit board or joint, as the board is soldered.
evaporation of oil, dirt, or any other substance from a surface after it is placed in a low pressure or vacuum environment.
The release of solvents and moisture from composite parts under a vacuum.
De-aeration or other gaseous emission from a printed circuit board when exposed to the soldering operation.
The release of a volatile substance from a compound during curing.
Primarily occurs in vacuum applications. The volatile (evaporative) components of some rubber compounds may vaporize in the vacuum and be released into the surrounding environment.
The passive liberation of a gas from any material.
The evolution of gas from a material in a vacuum.
the release of adsorbed or occluded gases or water vapor, usually by heating.
The act of printer ink solvents releasing gases as the ink cures.
A response to extreme conditions (e.g. high heat or the presence of a vacuum) to which the part is exposed. No relationship to by-products of the cure.
The process of evaporation that substances, such as oil and dirt, undergo after being placed in a low-pressure or vacuum environment.
The emanation of gas from a material. This process is usually enhanced in vacuum.
the release of gases or vapors by a material over time.
The tendency of some materials, e.g., acetate and nitrate film bases, to give off vapors as they decay. Some of these vapors may be harmful.
The vaporization and release of components (water vapor, plasticizers, air, inhibitors, etc.) in some rubber compounds due to pressure in a vacuum situation.
gradual release of gaseous molecules in a vacuum chamber that degrades long term vacuum performance. High performance vacuum designs avoid it by using vacuum grade materials and advanced vacuum processing techniques. See XP cooling technology.
Percentage of a gas released during the combustion of Insulation or jacketing material.
The process by which materials expel or release gasses.
Primarily occurring in vacuum situations, the volatile (evaporative) components of some rubber compounds may become vaporized in the vacuum and released (outgassed) by the compound into the surrounding environment.
Outgassing is the release of gases into the atmosphere during volcanic eruptions. A lot of of our atmosphere (including water vapor, nitrogen, and argon) came from outgassing.
Refers to gaseous emissions from solids or liquids, usually caused by exposure to high operating temperatures and/or altitude (low external pressure). Outgassing may come from absorbed gas, from the vaporisation of volatile contaminants, or from the breakdown of constituent materials. In a printed circuit board, outgassing may result in delamination; in a solder joint, outgassing during reflow may create voids.
Outgassing is the slow release of a gas that was trapped, frozen, absorbed or adsorbed in some material., Chapter 3 It can include sublimation and evaporation which are phase transitions of a substance into a gas, as well as desorption, seepage from cracks or internal volumes and gaseous products of slow chemical reactions. Boiling is generally thought of as a separate phenomenon from outgassing because it occurs much more rapidly.
