PM 800 Report Box N. 17 (in front of department
office)
Draw Brouwer diagram of MgO. (defect
concentration as a function of Po2) (assumption
1) Anionic Frenkel defects dominates the
intrinsic defect structure. (KFgtKi) (assumption
2) At high Po2, oxygen interstitial forms and
hole compensates the charge. (Method) Derive the
entire equations for drawing Brouwer diagram and
sketch the diagram. (You can see Fig. 2.11 in
Physical Ceramics by Prof. Y.-M. Chiang) Note
Do not use word processor for writing complex
equations! It will take long time. If you would
like to get high score, please describe the
physical meaning of equations.
