napalm
Napalm is flammable liquid used in warfare. It is a mixture of a gelling agent and petroleum or a similar fuel. It was initially used as an incendiary device against buildings and later primarily as an anti-personnel weapon, as it sticks to skin and causes severe burns when on fire. Napalm was developed in 1942 in a secret laboratory at Harvard University by a team led by chemist Louis Fieser. Its first recorded use was in the European theatre of war during World War II. It was used extensively by the United States in incendiary attacks on Japanese cities in World War II as well as during the Korean War and Vietnam War.
"Napalm" is a combination of the names of two of the constituents of the thickening/gelling agent: co-precipitated aluminium salts of naphthenic and palmitic acids.〔(【引用サイトリンク】title=Oxford Dictionaries - napalm: definition of napalm )〕 ''"Napalm B"'' is the more modern version of napalm and, although distinctly different in its chemical composition, is often referred to simply as "napalm".〔(Globalsecurity.org article )〕

Napalm was used in flamethrowers, bombs and tanks in World War II. It is believed to have been formulated to burn at a specific rate and to adhere to surfaces to increase its stopping power. During combustion, napalm rapidly deoxygenates the available air and generates large amounts of carbon monoxide and carbon dioxide.〔
Alternative compositions exist for different uses, e.g. triethylaluminium, a pyrophoric compound that aids ignition.
