SECTION 10: Stability and reactivity

10.1 Reactivity

The substance may ignite spontaneously on contact with air and moisture. This produces irritating or toxic fumes. Reacts with oxidants and many other substances. Reacts with moisture and acids. This produces flammable/explosive gas (hydrogen - see ICSC 0001). This generates fire and explosion hazard.

Reacts with water. This produces flammable/explosive gas (hydrogen - see ICSC 0001). This generates fire and explosion hazard. Contact with many other substances may cause dangerous reactions. Decomposes on heating. This produces toxic and irritating fumes.

10.2 Chemical stability

Slowly oxidizes in moist air.

10.3 Possibility of hazardous reactions

MAGNESIUM FIRE: DO NOT FLARE UP VIOLENTLY UNLESS...MOISTURE PRESENT. DANGEROUS IN FORM OF DUST OR FLAKES, WHEN EXPOSED TO FLAME OR BY VIOLENT CHEM REACTION WITH OXIDIZING AGENTS. ...SOLID FORM IS DIFFICULT TO IGNITE...IT MUST BE HEATED ABOVE ITS MELTING POINT... FINELY DIVIDED FORM...MAY BE IGNITED BY SPARK OR FLAME...OR EVEN SPONTANEOUSLY WHEN...DAMP, PARTICULARLY WITH WATER-OIL EMULSION. DURING MACHINING, MAGNESIUM FIRES RESULT FROM USE OF DULL CUTTING TOOLS, MACHINING WITH LIGHT CUT AT HIGH SPEEDS OR RUBBING OF TOOL ON WORK AFTER CUTTING OPERATION IS FINISHED.Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc.MAGNESIUM slowly oxidizes in moist air. Reacts very slowly with water at ordinary temperatures, less slowly at 100Â°C. Reacts with aqueous solutions of dilute acids with liberation of hydrogen [Merck 11th ed. 1989]. In the presence of carbon, the combination of chlorine trifluoride with aluminum, copper, lead, magnesium, silver, tin, or zinc results in a violent reaction [Mellor 2, Supp. 1. 1956]. A mixture of powdered magnesium with trichloroethylene or with carbon tetrachloride will flash or spark under heavy impact [ASESB Pot. Incid, 39. 1968]. Stannic oxide, heated with magnesium explodes [Mellor 7:401. 1946-47]. When carbon dioxide gas is passed over a mixture of powdered magnesium and sodium peroxide, the mixture exploded [Mellor 2:490. 1946-47]. Powdered magnesium plus potassium (or sodium) perchlorate is a friction-sensitive mixture [Safety Eng. Reports. 1947]. An explosion occurred during heating of a mixture of potassium chlorate and magnesium [Chem. Eng. News 14:451. 1936]. Powdered magnesium can decompose performic acid violently [Berichte 48:1139. 1915]. A mixture of finely divided magnesium and nitric acid is explosive [Pieters 1957. p. 28]. Magnesium exposed to moist fluorine or chlorine is spontaneously flammable [Mellor 4:267. 1946-47].

10.4 Conditions to avoid
