Imperfections are generally exist in lattice structurs of crystalline materials. In real life, there is no perfect crystalline materials that has zero imperfections inside their structure. In this article, we will explain the general imperfection situations in crystalline materials.
Imperfections in crystalline materials can be grouped into three; point defects, line defects and surface defects.
Point Defects; These defects are produced by situations from an individual atom, ion etc. in crystalline lattice structures.
Line Defects; These defects are produced by situations from a line of atoms, ions etc. in crystalline lattice structures.
Surface Defetcs: This defects are responsible of shape of the related crystalline structure. These are generally observed as grain boundries in crystals. These grain boundries are generally utilized in obtaining certain material properties in varios materials.
The general expression of imperfections in crystalline structures are like that. Leave your comments and questions below about this topic!
