Lead azide was a component of the six .22 (5.6 mm) caliber Devastator rounds fired from a Röhm RG-14 revolver by John Hinckley, Jr. in his assassination attempt on U.S. President Ronald Reagan on March 30, 1981. The rounds consisted of lead azide centers with lacquer-sealed aluminum tips designed to explode upon impact.

2009年3月3日 · Lead azide is an explosive chemical compound of lead used mainly in detonators. Lead is a heavy metal and stable element with the symbol Pb and the atomic number 82, existing in metallic, organic, and inorganic forms. It is mainly found in …

Colloidal lead azide is the purest form of lead azide used in the United States and is made by mixing dilute solutions of lead and azide salts. It has a very fine particle size of ~ 5 µm, making it ideal for its main application, which is as a coating on …

Lead azide, also known as lead(II) azide, is a chemical compound. Its chemical formula is Pb(N 3) 2. It contains lead and azide ions. It contains lead in its +2 oxidation state. Lead azide is an explosive. Most other azides just burn rapidly. It is used as a …

LEAD AZIDE is unstable. May, when dry, decompose explosively if shocked, heated or subjected to friction. Forms violently explosive products with carbon disulfide. Can be sensitized to explosive decomposition by metal salts (copper or zinc) or by traces of strong acids [Sax, 9th ed., 1996, p. 298]. An explosion occurred by mixing lead azide ...

2020年5月13日 · Lead azide is a white solid, poorly soluble in water and ammonia, but very soluble in acetic acid, more so if hot. It has a density of 4.71 g/cm 3 . Lead(II) azide decomposes at 190 °C and explodes if heated at higher temperatures.

Type of Lead Azide Product Characteristics; Service (SLA) [16,17,18]Service lead azide (SLA) was developed by the British and does not involve a coating agent; instead, it makes use of the addition of acetic acid and sodium carbonate, which provides a nucleus to precipitate lead azide in a less hazardous (compared to needle-shaped crystals) spherical morphology.

2024年12月18日 · Lead azide is prepared by the reaction of sodium azide with lead nitrate: 2NaN 3 + Pb(NO 3) 2 → Pb(N 3) 2 + 2NaNO 3. Production Methods. Lead azide crystallizes as colorless needles. It is a sensitive detonating agent, exploding at 350 °C. Lead azide is commonly prepared by the reaction between dilute solutions of lead nitrate and sodium azide.
