- Аннотация: Theoretical model for the simulation of synthesis of Janus-like particles (JP)consisting two different phases using the Carbon Combustion Synthesis of Oxides(CCSO) is presented. The model includes the variation of sample initial porosity,carbon concentration and oxygen flow rate used to predict the formation of JP features.The two temperature (2T) combustion model of chemically active submicrondispersedmixture of two phases including ferroelectric and ferromagnetic wasimplemented and assessed by using the experimentally estimated activation energyof 112±3.3 kJ/mol and combustion temperature. The experimental values allowedto account the thermal and concentration expansion effect along with the dispersionby the slip-jump simulation for high Knudsen numbers. The model predicted thatthe smaller initial porosity of the combustion media creates higher formation rateof Janus-like particles. The simulation of slippage and jumps of the gas temperatureallowed the scale-bridging between macro- and micro- structures.
