silver thermite


Has anyone here used a silver oxide/Al mixture. i can guess that it is highly sensitive, so i would like to know more aboutt it before i make it.

not to be a jerk... but try a little harder please.
googled: aluminum silver thermite
http://www.amazingrust.com/Experiments/how_to/Thermite.html

this came up as the first answer. took almost no effort at all. so don't take this as angry attack but a tip for the future.
common practice here might be to
1) make an appropriate title. seeing as how you are posing a question and have no info maybe put in a more descriptive heading "any one have experience with XXXX?"
2) try to come up with more than a one line question. in a clear concise manner a) here is what I have done.b) this is what I hope to accomplish,c) I have been reading these XXX, YYY, ZZZ, and it got me to thinking WWWW.d) does any one have any input?
maybe even throw a few equations or reactions up for clarity.
3) sign off perhaps with a direction you intend the info to lead.

that would be a fair investment of your time to persuade others to even bother chiming in. members such as I, like to read up on many things others do, and don't mind doing a little poking around if it is interesting. fun to learn things I wasn't into or knew about earlier.

start with the link I found and maybe post some interesting links you find with a little more effort. I would be glad to read up more on silver.

i would not think that it would be, though probably easier to ignite than regular thermite

waste of money, just use CuO

from my link above, a few for comparison:

Fe3O4/Al (-3.677 kJ/g)
Fe2O3/Al (-3.985 kJ/g)
CuO/Al (-4.584 kJ/g)
Cu2/Al (-2.421 kJ/g)
Ag2O/Al (-2.11 kJ/g)

ii did not meen to offend, i have already researched it but i wanted practical advice from people who have dealt with it. it only plan to make a gram of it to satisfy my curiosity.

This is a study published in combustion and flame journal. It deal with a thermite mixture of nano Ag2O and nano Al.

sorry but my computer(well actual a 2007 kindle( can't accept the download (it sucks). but thanks anyway.
i am going to use the thermite in a tall walled container then treat it with HCl to get little silver nuggets.

bismuthate,

you will be very disappointed if your intent is to dissolve the Ag from the products of an aluminothermic rxn.

Use of HCl will form a tenacious layer of AgCl over anything you end up with.

What are you trying to achieve/do with this idea?

If you want to get silver from the oxide, why not just heat it? It decomposes at 280 C, which is easily reachable with an alcohol burner or hotplate.

As below, so above.

You can use electrochemical means to produce shiny metal, if that is what you are after.

However, it doesn't take that much to melt silver. I got small amounts (20 grams or so) to melt with a cheap butane torch.
