Abstract
⺠Collapse of a silicoaluminophosphate molecular sieve by thermal aging was studied. ⺠Zeolite-LDA collapse occurs in the temperature range of 1000 to 1100 °C. ⺠Macroscopic morphology is retained throughout amorphization and recrystallization. ⺠A coordination change occurs in Al-polyhedra from six-fold to four-fold. ⺠SiO4 tetrahedra segregate from the AlPO4 lattice to form an amorphous silica phase.
