Difference between Point defect and Line defect
Difference between Point defect and Line defect are in tabular form below.
Point defect |
Line defect |
The irregularities that occur at or around a single point of the crystal lattice are termed as point defect. | Line defects form crystallographic defects in which the defects occur in a plane of atom. |
Point defects occur around a certain point of the crystal lattice. | line defects occur in the plane of atoms and in the middle of crystal lattice. |
These type of defect forms due to the pressure of extra atoms from the lattice. | These type of defects forms an edge of dissociation and screw dissociations.
Line defects are difficult to visualize. |
Thermodynamically stable compared with other kinds of defects. | Thermodynamically not stable as compared to point defects. |
In a pure metal two types of defects are possible that are intrinsic and extrinsic. | Line defects produce two types of dislocations: edge and screw dislocation. |
Point defects produce local distortion in a perfect lattice. | They have no local distortion. |
Examples of point defects are: Vancy, Schottky, defect, a Frenkel defect. | Examples of line defects are: edge dislocation and screw dislocation. |
