FIELD: machine building. ^ SUBSTANCE: proposed dope comprises industrial powder of metal selected from the group: aluminium, magnesium, and solid oxidiser. The latter represents nanosized powder of molybdenum trioxide with mean particle size no exceeding 100 nm produced by mechanical activation on industrial powder of molybdenum trioxide. Ratio of components is as follows, in wt %: metal powder - 30-70, nanosized powder of molybdenum trioxide makes the rest. Components are subjected to joint mechanical activation by mixing and milling in power-intensive ball mil in inert atmosphere. Note here that mechanical activation is performed in two step. At first step, molybdenum trioxide powder is minced to mean particle size not exceeding 100 nm. At second step, obtained nanosized molybdenum oxide powder is mixed with industrial powder of metal and subjected to another mechanical activation. ^ EFFECT: notably reduced self-ignition delay and higher rate of fuel-air mix combustion. ^ 3 cl, 6 dwg, 3 ex |
