What is non-stoichiometric defect? State its types.
(N/A) Non-stoichiometric defects occur when the ratio of constituent elements in an inorganic solid deviates from the ideal stoichiometric ratio due to defects in the crystal structure.
These are primarily classified into two types:
$(i)$ Metal excess defect
$(ii)$ Metal deficiency defect
