These oils typically use fractional crystallization ( separation by solubility at temperatures ) for the separation process instead of distillation.
22.
The intrusive complexes exhibit evidence of fractional crystallization and crystal segregation by settling or floating of minerals from a melt.
23.
The numerous felsic sections are associated with episodes of fractional crystallization in a high-level, zoned magma chamber.
24.
A composition from which they could reasonably be produced by fractional crystallization is termed a " parental melt ".
25.
To prove this, fractional crystallization models would be produced to test the hypothesis that they share a common parental melt.
26.
Other methods include the use of 4A MO sieves, aluminum tert-butylate, CaH2, or fractional crystallization under inert atmosphere.
27.
The magmas appear to come from a magma chamber at a depth of, and also underwent fractional crystallization and assimilation of crustal materials.
28.
These rocks apparently form by the extreme fractional crystallization of magnesian suite or alkali suite magmas, although liquid immiscibility may also play a role.
29.
A number of processes have been proposed to purify HfCl 4 from ZrCl 4 including fractional distillation, fractional precipitation, fractional crystallization and ion exchange.
30.
It was first discovered by Day and coworkers in 2002 as an inclusion complex containing CB [ 5 ] by fractional crystallization of the cucurbituril reaction mixture.
