Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
A crystalline material having, in the dehydrated form, the empirical formula: m(M 2/a O): X z O xz/2 : y YO₂ (I) in which m is 0.5 to 1.5; M is a cation of valency a; X is a metal of valency x, selected from aluminium, boron, gallium, zinc, iron and titanium; z is 2 when x is an odd number, and z is 1 when x is an even number; y is at least 5; and Y is silicon or germanium; and having, in the calcined hydrogen form, an X-ray diffraction pattern including significant peaks substantially as follows: d(Å) I 11.5 ± 0.25 VS 7.50 ± 0.15 M 7.20 ± 0.15 W 5.88 ± 0.12 S 5.73 ± 0.12 M 4.75 ± 0.10 M 4.58 ± 0.10 M/S 4.00 ± 0.10 W 3.95 ± 0.08 M 3.81 ± 0.08 M 3.75 ± 0.08 W 3.67 ± 0.08 W 3.58 ± 0.08 S 3.55 ± 0.08 S 3.49 ± 0.07 S 3.48 ± 0.07 M 3.14 ± 0.07 M 2.97 ± 0.06 W 2.93 ± 0.06 M 2.91 ± 0.06 W
