The thermal stability and dehydroxylation of the microporous silicoaluminophosphates H-SAPO-11, H-SAPO-18, H-SAPO-31, and H-SAPO-34 were investigated after thermal treatment at temperatures of 773-1173 K. While no change of the crystallinity upon thermal treatment at 1173 K was found by X-ray diffra
