| Abstract: | Nanosize SnO 2 powder with high purity of 98.8% was prepared by evaporating and coacervation method in DC arc plasma. The mechanism of oxidation reaction and particle growth in the plasma were studied. The process parameters in fluencing the particle size and purity of powder were also approached. The rate of SnO 2 powder with different average particles size from 40 nm to 150 nm can be obtained by controlling the pressure of reaction gas in the reactor and the cooling temperature of powder. |
