N2 - The occlusion of lithium, sodium, potassium and silver nitrates from the anhydrous melts in the respective zeolites has been studied by measuring the gain in weight and by direct analysis. The results in moles of occluded nitrate per formula weight of zeolite M12I[(AlO2)12(SiO2)12] are 11.7 for LiNO3, 10 for NaNO3 and 10 for AgNO3 and essentially zero for KNO3. A model is proposed for the structure of the occlusion compound Na22[(AlO2)12(SiO2)12(NO3)10], in terms of four NaI+ ions and four [NaI ‐ NO3 ‐ Na]+ groups at the apexes of the cubic unit cell and four [NaII ‐ NO3 ‐ Na]+1/3 groups coordinated with two [NaNO3]−2/3 groups at the faces, to explain the properties of the occluded zeolites.
