Abstract

Contrary to popular theories of the past, often in the ignition of aluminum vapor phase (gas reaction gas) would imagine, recent research suggests that some solid phase combustion reaction conditions effective role in advancing the process gas is combustible. To determine the role combustion of metal particles There are many ways. One of these methods of ignition time, and time changes with changing particle diameter, and its sensitivity to the amount of oxygen. experiments showed that the sizes below 50 microns, the role of gas solid reactions stronger than the gas phase reaction is gas.
