Abstract
The paper presents the results of theoretical and experimental studies of thermal plasma heating and melting of agglomerated powder based on quartz sand screenings of the Tugan Deposit, Tomsk region, Russia. It is shown that phase transitions significantly affect the process of thermal plasma heating and melting of agglomerated powder, which can lead to unjustified heating of particles. The results of thermochemical processes due to heating are presented herein. It is found that the total concentration of phases subjected to evaporation at the initial stage, is rather small (0.13 wt.%). The model is proposed for the hollow particle formation from silicon dioxide agglomerates.
