The tungsten powder is a perspective fuel for pyrotechnic mixtures used for different purposes. This is why the studying of characteristics of high temperature oxidization of or tungsten in different gaseous environments is so important. When the chemical reaction occurs on the surface of metals and the products of reaction (oxides) evaporates, the Stefan flow appear that has a substantial influence on the processes of high temperature heat and mass exchange and oxidization of particles. The problems reviewed in this work are: the influence of the Stefan flow on the processes of high temperature oxidization of the tungsten particle, also its influence on the ignition period t_(ign) and its integral parts: the time of inert heating t_(in) and the time of chemical heating t_(ch) (t_(ign)= t_(in+) t_(ch)). Also the influence of the Stefan flow on the temperatures of particles in these moments of time (T_(in), T_(ch)) and on the time of burning t_(burn) and the maximal temperature of burning of tungsten particle was researched.
