Solid Chemistry Problem
« on: December 14, 2006, 07:27:14 AM »
Give a possible reason for crystal defects?

I have surfed wikipedia, but it only display five kinds of crystal defects only.

Other websites says that it is because of 'free energy'.

But actually I don't know what it means, do anyone have any idea in reason of crystal defects?

Heating will increase crystal defects.

But I think the most possible reason for crystal defects is oxidation by atmospheric oxygen.

Do you agree?
