About Ivanyukite-Na-C
Formula:
Na2Ti4(SiO4)3(OH)2O2 · 6H2O
Colour:
Pale orange
Lustre:
Vitreous
Hardness:
4
Specific Gravity:
2.6
Crystal System:
Isometric
Member of:
Name:
Named in honor of Gregory Yur’evich Ivanyuk, Russian mineralogist and petrologist, head of the Laboratory of Self-Organized Mineral Systems in the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences.
First Recorded Locality:
A polytype of Ivanyukite-Na
Formed by partial hydration of ivanyukite-Na-T.
The structure of all ivanyukites is described as a 3D framework of the pharmacosiderite type; it is based on of four edge-sharing TiO6 octahedra connected by the silicate tetrahedra. It contains 8-membered rings defininng channels with an effective width of 3.5 Å. Na, K and water reside within the channels.
