Topics I've Started

Bp Question

19 July 2007 - 08:58 PM

Just thought it was interesting, but how much pressure (psi) do you think Bp can generate? I mean, if you somehow ignited a completely enclosed container filled with loose meal, how much pressure do you think it would build up? I know that density, the ratio of ingredients, quality of ingredients, and maybe even the particle size would effect it, but it would be interesting to know how pressurized it would be the instant combustion finished.

I did a search, and I didn't find anything similar to this, and I am curious. Any thoughts?

Mortar muzzle flash

10 July 2007 - 12:14 AM

I have been thinking, would it be possible to add an effect to the Bp lifting charge of a mortar, and make impressive enough to be worthwhile? I mean, add steel wool or aluminum powder to the lifting charge, and get a huge fountain (albeit very brief). Would the added heat damage the mortar possibly?

Also, what would be the best size of steel wool? Very fine or very coarse? Maybe 000-0000 for smaller mortars and 0-00 for larger ones, or a mixture sizes.

Homemade aluminum powder

18 May 2007 - 08:17 PM

It seems every forum but this one had a thread on it, so here goes...

For alot of people, (me), aluminum powder is really hard to get. Is there any way that it could be made fairly easily at home, using common household products?
I am aware of several of the existing methods, like using an angle grinder or salt and foil in a blender, but do these really work?
The preferred feedstock would be aluminum foil, as it it easy to get and very cheap.

The yield does not have to be very big, but a nice, fine mesh would be good.

Also, is it possible to ball mill aluminum? I suppose lead couldn't be used as a media, what about tungsten or steel?

I have always liked to make as much of my stuff as I can instead of buying it anyway. (Thinking sour grapes fable)

Pyro Uses for Iodine

08 May 2007 - 01:35 AM

I was wondering, disregarding the cost of iodine, if one replaced the chlorine in a compound with iodine, would there be any significant differences? (increased reactivity, different colors, and other interesting things)

One step further, what about replacing chlorine with any of the halogens? Florine is insanely reactive, but this could be a problem, as it would be hard to break the bonds to start the reaction.

Purifying common chemicals

30 April 2007 - 12:08 AM

When purchased from chemical supply companies, most chemicals are very pure. But this is expensive, and takes time (plus you get put on "lists"). Many chemicals are available at the local gardener's or hardware store, but at low purity. (90%dusting sulfur, potassium nitrate weed killer) Could it be possible to fairly easily purify these chemicals available locally?
