Abstract
The atom distribution on several aluminosilicate frameworks has been a nalyzed by using a Monte Carlo method with a lattice gas model. The at om ordering is found to be dependent on the network topology, and, in particular, on the number nz of next nearest tetrahedra in the network . For equal atomic fractions of Al and Si, increasing n(2) favors long -range order in the atom distribution.
