About ZincsiliteHide

Formula:
Zn3(Si4O10)(OH)2 · 4H2O
Colour:
White, bluish
Lustre:
Pearly
Hardness:
1½ - 2
Crystal System:
Monoclinic
Member of:
Name:
Named after its composition containing zinc (Zn) and silicon (Si)
Smectite Group. A tetrasilicic member of the smectite group. When Al(IV)
substitutes for Si(IV), charge imbalance requires an interlayer cation and the mineral may grade toward sauconite.


Classification of ZincsiliteHide

Approved
9.EC.45

9 : SILICATES (Germanates)
E : Phyllosilicates
C : Phyllosilicates with mica sheets, composed of tetrahedral and octahedral nets
71.3.1b.8

71 : PHYLLOSILICATES Sheets of Six-Membered Rings
3 : Sheets of 6-membered rings with 2:1 clays
14.7.13

14 : Silicates not Containing Aluminum
7 : Silicates of Ba, Sr and Zn

Physical Properties of ZincsiliteHide
