Point defects in ceramics.
Frenkel defect point defect in ionic crystal ceramic frenkel defect is one type of point defect.
Usually this type of defect is observed in ionic solids where size of anion is substantially larger than the size of cation.
This concept now plays a vital role in the physics and chemistry of ceramics.
And the we can find the two different types of point defect.
The point defect which dissolve the crystal pattern at an isolated site.
At some point every potter will encounter one or more of these common defects.
Ceramics defects common clay body and glaze defects.
It is not only with respect to ionic conductivity but also with respect to diffusion general reactivity creep optical behavior radiation damage and many other phenomena.
In fact it is a combination of both vacancy and interstitial type of point defects.
This chapter outlines the concept of point defects.
The first is intrinsic point defect which can be formed when an atom is missing from a position.
