Re: CS>Silver crystal structure & Startrek's Borg Cube

[Ode Coyote]

Synonyms

silver (I) chloride
silver chloride

Physical properties

Colour: white
Appearance: crytalline solid. Light sensitive.
Melting point: 455°C
Boiling point: 1550°C
Density: 5560 kg m-3

####Interesting.
Perhaps the old way of making CS with a pinch of salt does make the CS sensitive to light.
CS made without the salt is not.

Formula as commonly written: Ag2O
Hill system formula: Ag2O1
CAS registry number: [20667-12-3]
Formula weight: 231.736
Class: oxide

Synonyms

silver (I) oxide
silver oxide
disilver oxide

Physical properties

Colour: black to brown black
Appearance: crystalline solid
Melting point: 460°C (under 1 atmosphere oxygen)
Boiling point:

## I have had extremely strong and quickly made CS go black or brownish.
Using fresh ozonated water seems to promote color changes.
Could deep yellow or brownish have anything to do with oxidation?
Could a silver crystal be partially oxidized like a piece of steel partially rusted?
..and could several crystals organize around an oxygen atom...being that one has a net positive charge and the other a negative charge. Would this lead both to a larger particle AND a change in color?
