FIELD: measuring.
SUBSTANCE: invention relates to the field of nanotechnology of materials and can be applied in researching the properties of multi-layered reaction materials with a self-propagating high-temperature synthesis (SHS) effect, in particular, for determining the propagation speed of the burning front of such materials. Proposed is a method for determining the speed of the burning front of multi-layered reaction nanofilms, based on using an oscillograph receiving an electrical signal from a photodiode when the burning front passes, characterised by the fact that the electrical signal transmitted to the oscillograph is received from a load resistor connected in series with a strip of the multi-layered reaction nanofilm, connected to an electric current source, and the burning speed of the multi-layered reaction nanofilm is determined by the time of change of the voltage on the load resistor by the formula wherein V is the speed of the burning front, is the length of the nanofilm strip, t is the time of change in voltage on the load resistor (the burning time of the nanofilm strip).
EFFECT: purpose of the invention is development of a simple method for determining the propagation speed of the burning front exhibiting high accuracy and low implementation (material and time) consumption.
