Colored crystalline aluminophosphates and/or silicoaluminophosphates of the AEL or VFI type

摘要

Colored crystalline alumophosphates and/or silicoalumophsophates of the AEL or VFI type useful as dyes, optical elements and as adsorbents have the following X-ray diffraction diagram: -Interplanar spacing Relative intensity -d(A) I/Io x 100 -10.91 +/- 0.1 26 +/- 10 -9.19 +/- 0.1 41 +/- 10 -6.79 +/- 0.05 16 +/- 10 -5.57 +/- 0.05 52 +/- 10 -4.39 +/- 0.05 39 +/- 10 -4.18 +/- 0.05 71 +/- 10 -4.09 +/- 0.05 33 +/- 10 -3.98 +/- 0.05 57 +/- 10 -3.86 +/- 0.05 68 +/- 10 -3.81 +/- 0.05 100 - and a composition described by the following formula: a quinizarin.b Al2O3.c P2O5.d SiO2 where a is from 0.05 to 2, b and c are each from 8 to 12, and d is from 0 to 4.
