Point Defects In Ceramics

The first is intrinsic point defect which can be formed when an atom is missing from a position.
Point defects in ceramics. This concept now plays a vital role in the physics and chemistry of ceramics. At some point every potter will encounter one or more of these common defects. So in this scheme you can find the two different types of intrinsic point defect. Usually this type of defect is observed in ionic solids where size of anion is substantially larger than the size of cation.
In order to solve the problem it is important to diagnose the defect correctly and make the appropriate correction. The point defect which dissolve the crystal pattern at an isolated site. Frenkel defects schottky defects. In fact it is a combination of both vacancy and interstitial type of point defects.
And the we can find the two different types of point defect. 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. Ceramics defects common clay body and glaze defects.
