Cool ...and throwing this "visualization" out there again... Could it be that HV AC or DC does something similar to sputering such as in electro or flame deposititation as done to steel with zinc and other metals?* I would expect the ionic content to be low to non existant and the TE to be very strong.
Possibly such a particle has no real crystaline structure as it wasn't formed by ions agglomerating [didn't "grow"] and is just a roundish ball of pure silver. A mirror is still a mirror no matter what the size. [Well..seems reasonable] Sometimes it is difficult to determine what the actual color of 'clear' CS is because it tends to reflect all the colors around it. The predominant color in my house is yellow [lots of yellow pine] so, sometimes i have to take the CS out in the sun and surround it with white paper in order to confirm that is has no color. So, just maybe, the various colors of particles produced by way of agglomeration of ions has to do with differing crystal lattice structures that changes the shape of the reflecting surface and may include other componants such as silver oxides and that's why light refracion is different for the various sizes of particle made that way. Sure, smaller/larger particles may absorb different wavelenghts of light and refract or reflect others..but why? [something related to light polarization pops into mind as a possibility..or..if you make a bank shot in billiards and can only see the ball that's headed straight at you, the darned thing could dissappear] Perhaps H2O2 breaks the oxides [or whatever] out of the crystal thus destructively reducing the size of the particle [by taking a few rungs out of the ladder], tossing some of it off as ionic and some as smaller metallic particles with different surface reflection characteristics. [hence the fairly strong TE in my liter of 'no longer' violet bottle of CS] And maybe that's why stirring, various ion production rates/current, water temperature and even storage temperature in the first few days can have such an effect on what colors of particles that result and why they can change with time, along with drops in conductivity while in storage. Bottom line being that size and color of "grown" particles do have a correlation but for reasons as yet to be discussed. If a particle is electro-sputered in an inert gas, it wouldn't take on any oxygen or other air componants and remain something like a shiny ball bearing. [Molybdenum sulphide lubricants come to mind..micro ball bearings in oil] *[one method of corrosion protection is to take 2 zinc wires with electrical power, make them arc while blowing high pressure air through the arc to deposit zinc on steel..another is to release small metallic particles into an oxy acetylene flame to deposit metals.... "powder metallurgy", The resulting surface has a blobby bumpy appearance under a microscope that can be machined smooth. In its travel through the air, other gas medium or a vacuum, the small molten blob forms a ball just like it was dropped from a shot tower. A crankshaft, for instance, can even be case hardened with tungsten carbide. ] Ken At 12:56 PM 8/1/01 -0500, you wrote: >Ken; > >I have the data sheets and theTEM for CS made with 380 v dc. the CS is colorless just like water but the TEM from Texas >show particle size ranging form 18 nm to about 86 nm. Somuch for particle size and color.
