Preeti Dabral 8 months, 3 weeks ago

Metal Deficiency defect: It is caused due to cation vacancy created by replacement of some valent ions by its higher charge ions. Example FeO with Fe³⁺. Where Fe²⁺ and Fe³⁺ both are present in lattice.

Mayank Rai 6 months, 1 week ago

It is a type of defect which occurs due to the absence of cations from the lattice site. The defect occurs when the metal has variable valency.
