THERMITE FUEL COMPOSITION Russian patent published in 2011 - IPC C06B33/12 

FIELD: chemistry.

SUBSTANCE: invention relates to small-scale heat-power engineering, particularly thermite fuel compositions which, during initiation, can undergo chemical conversion with release of a large amount of heat, and mainly to such compositions which do not detonate and in which redox reactions take place in air in combustion mode without a special oxidising agent and without formation of a liquid phase. Aluminium oxide and aluminium are added to the thermite fuel composition in form of nanopowder in the following ratio in wt %: aluminium oxide nanopowder 1.5-3.0; aluminium powder - the rest. During combustion of the disclosed thermite, a liquid phase does not form and there is no fusion with the substrate.

EFFECT: high heat-liberation value of the thermite fuel and low content of liquid phase in combustion products of this fuel.
