Investigation of the Possibility for Control of High-Temperature Synthesis of Nanomaterials

What is it about?

Experiments were carried out to determine the velocity of the combustion wave propagation of aluminum nanopowder obtained by electric explosion of wires. The factors influencing formation of the induction time were considered: the thermal diffusivity of the substrate, the method of initiation of the combustion wave (flame, spark, heated body), the induction time between the initiating front and the front of the thermal explosion. The relation describing the time of induction of thermal explosion is established.
