“recrystallization”的概念、定义、翻译、参考文献-科学参考

recrystallization

Chemistry

A process of repeated crystallization in order to purify a substance or to obtain more regular crystals of a purified substance.

Chemical Engineering

1. A process used to purify a substance or to obtain more regular crystals of a purified substance by repeated crystallization.

2. A solid-state process that involves the reformation of the lattice structure of a crystal. It requires a rapid diffusion to the lattice and is carried out at an elevated temperature but below its melting point temperature. The homologous temperature is the absolute temperature as a fraction of (p. 320) the melting point also in absolute temperature. Recrystallization typically takes place at a homologous temperature of 0.6.

Geology and Earth Sciences

1. The growth of new mineral grains from pre-existing mineral grains by the solid-state diffusion of ions in response to a change in temperature, pressure, or composition of the rock system.
2. The changing of crystal fabric or crystal size without an accompanying change in mineral chemistry.
3. See fossilization.
