【求助】涉及间隙、激活能、缺陷方程式的问题
|
|||
|
内容涉及间隙、激活能、缺陷方程式。 2.4.2 (a) Calculate the radius of the largest atom that can exist interstitially in BCC iron (RFe=0.1241nm) without crowding. (b) What is the coordination number of the interstitial site? (c) How many of these sites are there per unit cell? 2.4.5 At 800℃, 1 out of 10^10 atoms, and at 900℃, 1 out of 10^9 atoms have sufficient energy for movements within a solid. (a) What is the activation energy in J/atom? (b) In cal/mol? 2.4.13 (a) Suppose that Li2O is added as an impurity to CaO. If the Li+ substitutes for Ca2+, what kind of vacancies would you expect to form? How many of these vacancies are created for every Li+ added? Write the defect equation. (b) Suppose that CaCl2 is added as an impurity to CaO. If the Clsubstitutes for O2-, what kind of vacancies would you expect to form? How many of the vacancies are created for every Cl- added? Write the defect equation. [ Last edited by NJUT_tiger on 2008-12-29 at 15:13 ] |
