Zorite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Na8(Ti,Nb)5(Si6O17)2(OH,O)5 · 14H2O
System:
Orthorhombic
Colour:
Rose-red
Lustre:
Vitreous

Name:
From Russian "zoria", meaning "the rosy radiance of the sky at dawn", alluding to its colour.
The structure of Zorite contains double dreier chains of (SiO4) tetrahedra, which are linked by Ti cations into a three-dimensional framework.
A topologically identical framework is found in the structures of Haineaultite (the Ca-analogue of Zorite), Chivruaiite, and the synthetic Zorite analogue ETS-4 (Men'shikov et al., 2006).
