Magnox (alloy), whose name is an abbreviation for "magnesium non-oxidizing", is 99% magnesium and 1% aluminium, and is used in the cladding of fuel rods in magnox nuclear power reactors. Magnesium alloys are referred to by short codes (defined in ASTM B275) which denote approximate chemical compositions by weight.
However, the effect only affects alloys with more than 0.8% Mg2Si (excluding Mg or Si surpluses) and alloys with more than 0.6% Mg2Si if Mg or Si surpluses are present. To prevent these negative effects, AlMgSi can be annealed after quenching at 80 °C for 5–30 minutes, which stabilizes the material condition and temporarily does not change.
The 20th CBRNE Command was activated 16 Oct. 2004, by U.S. Army Forces Command to provide specialized CBRNE response in support of military operations and civil authorities. [ 1] Its establishment consolidated a range of unique CBRNE assets from across the Army under a single operational headquarters at Aberdeen Proving Ground, Maryland.
Magnesium oxide ( Mg O ), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide ). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O ...

The SNL was an inventory system used from 1930 to 1958 to catalog all the items the Army's Ordnance Corps issued. The AIC was used by the United States Army Ordnance Corps from January, 1942 to 1958. It listed munitions and explosives (items from SNLs P, R, S, and T), items that were considered priority issue for soldiers in combat.

Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2.
