Abstract
A new zeolite material designated Nu-3 having a molar composition expressed by the formula: 0.5 to 1.5R.sub.2 O:Y.sub.2 O.sub.3 :at least 5XO.sub.2 :0 to 400H.sub.2 O wherein R is a monovalent cation or 1/n of a cation of valency n where n is a whole number of 2 or more, X is silicon and/or germanium, Y is one or more of aluminium, iron or gallium and H.sub.2 O is water of hydration additional to water notionally present when R is H, and having an X-ray diffraction pattern substantially as shown in Table 1, is prepared from a reaction mixture containing XO.sub.2 (preferably silica), Y.sub.2 O.sub.3 (preferably alumina) and an optionally substituted quinuclidinium ion.
