It should be pointed out that this optimized condition accords with the study of Kantor[18],whichspecifiedthattheparticlesizeof a dry aerosol produced during the heating process is inversely proportional to the vaporization temperature. With the vaporization temperature of 2500 °C and 2700 °C for wall vaporization and platform vaporization, respectively, the dry aerosol obtained by platform vaporization are smaller than that obtained by wall vaporization in particle size. Thus a higher auxiliary carrier gas flow is preferred for the transportation of bigger aerosol particle in wall vaporization.
