Note the white purified camphor on the cold finger, and the dark-brown crude product. Dark green crystals of nickelocene , freshly sublimed on the cold finger of the sublimation apparatus. A typical sublimation apparatus separates a mix of appropriate solid materials in a vessel in which it applies heat under a controllable atmosphere (air ...
Dark green crystals of nickelocene, sublimed and freshly deposited on a cold finger Sublimation of iodine. 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]
That is, any snow that falls in that area is counteracted by sublimation or other losses. Such areas are known as blue-ice areas . [ 3 ] These areas have been used as blue ice runways (e.g. Wilkins Runway , Novolazarevskaya , Patriot Hills Base Camp ) due to their hard surface, which is suitable for aircraft fitted with wheels rather than skis .
The sublimated material collects (5) on the cold finger proper, cooled by a coolant (blue) circulated through ports 1 and 2. A cold finger is a piece of laboratory equipment that is used to generate a localized cold surface. It is named for its resemblance to a finger and is a type of cold trap. The device usually consists of a chamber that a ...

In most of Antarctica, the net tendency is for snow to accumulate except in coastal Antarctica where melting occurs and blue-ice areas where sublimation dominates. [1] This sublimation occurs at rates of 3–350 centimetres per year (1.2–137.8 in/year) snow water equivalent and is balanced by ice flow, with the sublimation rate decreasing ...
