Question

how can we minimize defects in crystal lattice ?​

Answer 1

${\red{\huge{\bf{\underline{ANSWER:}}}}}$

There are basic classes of crystal defects: Point defects include lattice vacancies, self-interstitial atoms, substitution impurity atoms, and interstitial impurity atoms. linear defects, which are groups of atoms in irregular positions. Linear defects are commonly called dislocations.

Answer 2

Explanation:

In any sort of discussion of crystalline materials, it is useful to begin with a discussion of crystallography: the study of the formation, structure, and properties of crystals. A crystal structure is defined as the particular repeating arrangement of atoms (molecules or ions) throughout a crystal. Structure refers to the internal arrangement of particles and not the external appearance of the crystal. However, these are not entirely independent.
