What is lead azide used for?

What is lead azide used for?

Lead azide is an explosive. Most other azides just burn rapidly. It is used as a detonator to detonate other explosives. It is made by reacting lead(II) nitrate and sodium azide.

Is lead azide a high explosive?

Lead(II) azide is considered to be a highly sensitive explosive and has been classified into the first group of safety precautions [23].

How do you make lead azide?

Lead(II) azide can be prepared by adding an aqueous solution of lead(II) nitrate to a solution of sodium azide. Due to its low solubility, lead azide precipitates out of the solution. The precipitate is filtered, washed with anhydrous ethanol and air dried.

Why is dextrin added to azide?

The dextrinated products are generally superior to the forms of lead azide obtained from processes which do not employ dextrin, since the employment of dextrin leads to the suppression of the undesirable beta modification of lead azide and the absorption of inert dextrin by the lead azide reduces the sensitivity of the …

Is lead azide toxic?

Lead azide Pb(N 3) 2 is an inorganic compound. More so than other azides, Pb(N 3) 2 is explosive. It is used in detonators to initiate secondary explosives. In a commercially usable form, it is a white to buff powder….Lead(II) azide.

Main hazards Harmful, explosive

Why lead azide is treated as an explosive?

Lead azide was chosen due to its explosive characteristics (very sensitive, which increase risks of detonations but makes it a mandatory compound in almost every explosive use), intense use and the presence of lead in the raw materials (in the form of lead nitrate) and residues.

What is the safest primary explosive?

Dextrinated lead azide (DLA) (refs. 4 through 6) is considered to be the safest-to-handle form and the most common type now used commercially. It was developed in the United States in 1931 (ref. 4) as a solution to the numerous accidental explosions associated with attempts to manufacture pure lead azide.

How many Nitrogens does lead azide contain?

three nitrogen atoms
In organic azides, the three nitrogen atoms are connected to a carbon atom and in inorganic azides they are connected to a metal such as sodium or lead.

Was dynamite used in coal mines?

Although the major causes of coal mine explosions were known, particularly since studies were made by Britain and other European countries, many in the U.S. coal mining industry were not convinced. Black blasting powder and dynamite continued to be used and could not be made safe for blasting in underground coal mines.

Can you burn PETN?

93% TMD PETN in Steel – Piston Impact Ignition The burn is steady and traverses the entire length of the tube without any indications that it will transition to detonation. However, the compressive burn completely consumes all of the PETN and also does significant damage to the tube.
