Slush
As Slush is referred to a slurry-like mixture of a solid and a liquid phase of the same substance. The word comes from the English slushed ice , which means something like "mud ice" (slush = silt).
geomorphology
In geomorphology , the term “slush” is used to denote “mobile”, water-saturated snow in the periglacial areas determined by permafrost . Thawed by the sun and possibly saturated by rain, slushes can appear both continuously flowing and suddenly slide off.
gas
The term is also applied to gases that have been partially liquefied and partially solidified by cooling to their melting point , since the resulting mixture of liquid and solid phase has a mushy, muddy consistency.
Nitrogen , which is cooled to about −210 ° C, forms nitrogen slush . This can be used for shock-freezing objects, for example in preparation for electron microscopy .
fuel
Hydrogen , which when cooled to −259 ° C changes into a sludge-like state - slush hydrogen - was seen in space travel as a means of increasing the energy density of liquid hydrogen. Due to major handling difficulties caused by the negative pressure (70 mbar absolute), however, it was largely abandoned.
