A two-stage high-temperature incendiary (HTI) releasing halogens and hydrogen halides for fighting chemical and biological payloads is known as HTI-J-1000 [15, 16]. 

Duration of burning The incendiary materials must not only impart high temperatures but also maintain heat generation without replenishment of fuel. The heat must continue to radiate for an appreciable time and when the heated object is ready to bum, the fire must be present to ignite it. In fact two factors viz. intensity of heat and duration of burning are complementary to each other and must satisfy the purpose of incendiary materials. 

Thermal Effects — High temperatures are produced (300 - 3500 C) and may be sustained for relatively long periods of time, thus severe burns and incendiary effects are likely. 

An interesting combination of incendiary actions is the subject of a German patent which claims thermitic high-temperature reactions between aluminum ( PyroschlifT ) or calcium silicide, with phosphates such as tertiary calcium phosphate as the oxidizer. Since phosphides are the products of reaction, the application of water during Are fighting will cause formation of self-flammable phosphine. It would appear that such secondary action might be more of a nuisance than tactically efficient. 

The reaction is highly exothermic. Thermite is another major incendiary. It is a mixture of aluminum metal in powdered or granular form and a powdered iron oxide combined with a binder. When heated to combustion temperature of aluminum the reaction which is highly exothermic produces aluminum oxide and iron, generating temperatures as high as 2200°C (3992°F). 

A1 + Fe203 —> AI2O3 + 2Fe The reaction is highly exothermic and the increase in temperature is sutBcient to melt the iron produced, it has been used for localized welding of steel objects (e.g. railway lines) in the Thermit process. Thermite is also used in incendiary bombs.
