Arkhipov Vladimir Afanasyevich, Bondarchuk Sergey Sergeyevich, Zhukov Aleksandr Stepanovich

Information About Author:

Aspects of integrated effects of plasmatron mode parameters and heat-transfer medium properties on formation and evolution of droplet medium of injected solution by means of diffusion, filtration and heat transfer are considered. Mathematical model as well as calculation results for dependence of particle size and its liquid core on heating rate and initial mass fraction of dissolved salt are presented.

Keywords: ceramic powders, metal oxides, plasma technology, barrel-type reactor, mathematical model, thermochemical controlled synthesis, precursor, concentration of equilibrium saturation, boundary of evaporation front, drop suspension, intra-drop diffusion
