Outgassing is a challenge to creating and maintaining clean high-vacuum environments. NASA and ESA maintain lists of materials with low-outgassing properties suitable for use in spacecraft, as outgassing products can condense onto optical elements, thermal radiators, or solar cells and obscure them. Materials not normally considered absorbent can release enough lightweight molecules to interfere with industrial or scientific vacuum processes.

Materials outgas by three mechanisms: release of absorbed gases (desorption from the bulk of the material), release of adsorbed gases (desorption from the surface only), and evaporation of the material itself. The former can be reduced by a bakeout, the latter is an intrinsic property of the material. Some outgassed materials can deposit on other surfaces, contaminate the vacuum system and be difficult to get rid of. Splet什么是Outgassing?
