The two stages involved in the formation of particles of a new phase.
Answer to Problem 1QP
The brief description of two stages involved in the formation of particles of a new phase is explained below.
Explanation of Solution
The two stages involved in the formation of particles of a new phase are:
- Nucleation
- Growth
Nucleation:
The development of very miniature nuclei of a new phase from the parent phase, similar to embryo is known as nucleation. There are two types of nucleation, heterogeneous and homogeneous nucleation.
In heterogeneous nucleation, nuclei produce at non-homogeneous structures, like surface of container, boundaries of grain and so on.
In homogeneous nucleation, nuclei or particles produce within parent phase.
Growth:
The growing phase of the particle is called as growth. In this phase, the particles transform into a stable nucleus and the size of embryo got bigger than the decisive shape. The process of growth forms a new phase nuclei within the parent phase. The process of growing continues till the new formed nuclei got stable and replace the parent nuclei.
