Abstract
Zorite is a microporous titanosilicate, with ideal chemical formula Na6Ti5Si12O36.11H2O, reported for the first time in the Lovozero massif by (Mer’kov et al. 1973). Sandomirskii and Belov (1979), while recognizing the OD character of zorite, solved its superposition (family) structure in the space group Cmmm based on a unit cell with a=23.241Å, b=7.238Å and c=6.955Å. The same authors inferred a likely doubling of b and c parameters, based on precession photographs, and suggested several models for the possible OD maximum degree of order (MDO) polymorphs.
