Thread: Lead Azide(from Sodium Azide)

Materials:
- Separating funnel
- Scale
- Hotplate (preferably with magnetic stirrer)
- Water bath
- Beaker
- Filtering funnel

Chemicals:
- Sodium azide
- Lead (II) nitrate
- Dextrin
- Sodium hydroxide

Procedure:
An amount of 2.33 grams of sodium azide and 0.06 grams of sodium hydroxide are placed in a separating funnel and dissolved into 70 ml of water. Some shaking can be applied to mix and dissolve the chemicals. This is solution A. Then, 6.90 grams of lead (II) nitrate and 0.35 grams of dextrin are dissolved into 90 ml of water in a beaker or erlenmeyer. This is solution B. Put the beaker containing solution B into a water bath, and warm on the hotplate to 60 degrees Celsius. When warm, add solution A to solution B under constant stirring. The drop rate should be between 2 and 3 drops a second, and adding the solution should be finished in about 10 minutes. A white precipitate should form, this is lead azide. Filter the solution, and rinse 4 times with 50 ml water. Dry the residue for 15-18 hours at 65 degrees Celsius.

I didnt take any pictures while I was making it, but will next time(eather if i make it again by sodium azide that was bought or if i attempt to make it from Hydrazine on)

anhydrous Hydrazine? Were you planning on making Astrolite(i think thats what it was called) i ran into some information on its manufacture about a year or so ago. If your interested i'll see if I can find it.
