Have you ever heared of lead fulminate?
It must have formula Pb(ONC)2 and have similar properties of Hg(ONC)2?
It must be prepared by adding ethanol to mixture of lead nitrate in HNO3?
Is it critical sensitive like Ag(ONC)
Why i never heared of it...

Well you could have a fulminate of any heavy or unreactive metal which would be explosive. Also azides, some nitrides, picrates, styphanates, carbides, picramates and the list goes on ...... use your immagination. :D

I'm asking it because i don't know can lead fulminate substitute the unstable peroxides and the expensive azides in homemade detonators?
It is interesting why it is made Hg fulminate and Pb azide, not Hg azide and Pb fulminate?

There are a great range of fulminates (which are primary explosives) that can be prepared. I don't know the stability of lead fulminate, but it is probably similar to mercury fulminate. However the only fulminates that can be prepared from a metal nitrate in initric acid reacting with ethanol are mercury fulminate and silver fulminate. The others must be made from silver or mercury fulminate.
There was a topic some time back (called "other fulminates" i think) that covered this in detail.

Guys is there anyway of converting Hg(SCN)2 to our friend Hg(OCN)2. cause there is a thingy sold (I am not too sure if this is still sold)for kids called "serpants" or something. It has a mix or Hg(SNC)2 and NH4Cr2O7. <a href="http://www.webelements.com/webelements/elements/text/Hg/key.html" target="_blank">http://www.webelements.com/webelements/elements/text/Hg/key.html</a>
Click on the video clip, if you still don't know what I mean. The URL might need to be cut and pasted in your browser. They also have a clip of NI3 in the Iodine section.
If possible one would have all the Hg fulminate they need. :D
RED .... If your wanting to make cynates of Pb, Cu etc. do it via the cyanic acid + ?(CO3)x or ?(OH)x to get the ? fulminate. or acquire Na or K or NH4 cynate and mix with ?'s H2O soluble salt soln. I have the prep of Cyanic acid lying around but you'll probably find it on the forum itself.

Cyanates aren't the same as fulminates, sadly. And the mercury-containing snake fireworks have been unavailable for decades. "Back to the old drawing board."

Yo Polverone. What is the difference between cyanate and fulminate ? Anyone tell me. I always thought they were the same ... fulminate being the common name. :confused:

Cyanates have the C in the middle, OCN-.
Fulminates have the N in the middle ONC-.
Altogether a much less stable state.
When covalently bonded the term iso indicates the alternative atom is being bonded. Thus C2H5-NCO is ethyl isocyanate, C2H5-NC is ethyl isocyanide.

Stay safe.

So then Marvin, cyanates and organic iso-cyanates are the same according to the C being in the middle rule and ethyl iso-cyanate example ? :confused:
Which one of the following can be used to make Pb fulminate ? Na cyanate or the iso-cyanate or fulminate cannot be made by interacting salts. :p I need more bonding detail if possible.

i believe lead fulminate is used as a mix to gasoline engines, i do remember hearing about a chemichal that when one pint added to 10 gallons of unleaded fuel will increase by atlease 10 horsepower. im pretty sure it was lead fulminate.

Unfortunately you are quite wrong. The compound you heard about is called tetra ethyl lead and it's used to increase the octanic number (which will DECREASE the premature detonations of the gasoline, hence increasing the engine power). In other words, making gasoline HARDER to burn. It's a organic compound containing a metal.
It was choosen because the scientists concluded that a heavy metal compound is needed, and the coupound should be soluble in gasoline.
