Abstract: Crystalline zeolite powder of type A(II) is prepared from an NaOH soln. (1), an alkali silicate soln.(2), and an alkali aluminate soln.(3) of Al2O3 and Na2O. The product has a composition of 1.0±0.2 M2/nO : Al2O3 : 1.85±0.5 SiO2.yH2O, where M = metallic cation, n = atomic value, and y = number up to 6. 50 wt.% of a powder having a size less than 4.8.μ (1) is heated up to 30-100≦̸C; (2) is introduced for 10-200 min.; (3) at a temp. of 30-100≦̸C is mixed with the soln.; and the soln. mixture is crystallized at a temp. of 20-115≦̸C for more than 15 min.

Abstract: Crystalline zeolite powder of tyep A(IV) is prepared from H2O(1), a sodium aluminate soln.(2) of Na2O and Al2O3, and a sodium silicate soln.(3) of Na2O and SiO2. The crystallized product in a gel contg. the premixture has a compsn. of 1.0±0.2 M2/nO : Al2O3 : 1.85±0.5 SiO2.yH2O, where M = sodium cation, n = atomic value, and y = number up to 6. 50 wt.% of a powder having a size less than 5.0μ . The compsn. of the premixture is SiO2/ Al2O3)= 2 - 50 : 1, Na2O/SiO2 = 0.2 - 20 : 1, and H2O/Na2O = 4-300 : 1.

Abstract: Crystalline zeolite powder of type A(I) is prepared from heated sodium silicate soln. (1) by mixing it with sodium aluminate soln. (2) in two stages. The product, having a composition of 1.0±0.2 M2/nO: Al2O3: 1.85±0.5 SiO2yH2O (where M = Na+ ion, n = valency, and y = 0-6), is obtained by crystallization of the synthetic mixture for 15 min. at 20-175≦̸C 50 wt.% of the particles have a diameter less than 4.0 microns. (1) contains Na2O and SiO2, and (2) contains Al2O3 and SiO2.

Abstract: Crystalline zeolite powder of type A(III) is prepared in two stages from a heated sodium aluminate soln.(1) containing Al2O3 and Na2O and by the addition of a sodium silicate soln.(2) containing Na2O and SiO2. The product, having a composition of 1.0±k0.2 M2/nO: Al2O3: 1.85±0.5 SiO2yH2O (where M = Na+ ion, n = valency, and y = 0-6), is obtained by crystallization of the synthetic mixture for 15 min. at 20-175≦̸C. 50 wt.% of the particles have a diamter less than 4.3 microns.
