About Zorite
Formula:
Na8(Ti,Nb)5(Si6O17)2(OH,O)5 · 14H2O
Colour:
Rose-red, pink, can appear white or colourless in individual crystals.
Lustre:
Vitreous
Hardness:
3 - 4
Specific Gravity:
2.27 - 2.40

Orthorhombic
Member of:
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).
