Hello everyone,
 I wonder if somebody has managed to define an approximate crystal structure for
 gamma-Al2O3? I know that it is highly amorphous, but at the microscopic level I
 would expect there to be some order. I have read somewhere that it has an
 approximate spinel structure with Al vacancies.
 Since gamma-Al2O3 is a widely used support material for catalysts, I would
 expect that some theoreticians have tried to define a model which resembles it?
 Best regards
 Merethe
