Modeling the One-Stage Synthesis of Composite Particles of the Nucleus–Shell Type in Separate Oxidation of Titanium and Silicon Tetrachlorides in a Plasmachemical Reactor

Abstract

The authors have modeled the one-stage synthesis of titania and silica composite nanoparticles in the working zone of a plasmachemical reactor by the chloride method based on separate oxidation of titanium and silicon tetrachlorides with pre-mixing of the reagents by bubbling. Within the framework of the developed synthesis model, the authors have obtained data on the size of the nuclei of the composite particles, the shell thickness, and the ratio of the number of shell-coated and uncoated particles.
