Effects of flame temperature and SiCl₄ concentration on particle characteristics for synthetic silica glass

Abstract

Effects of flame temperature and SiCl₄ concentration on the particle characteristics were studied. The flame temperature distributions were measured using modified sodium line-reversal technology. The particles were collected by quartz supports and were analyzed by scanning electron microscope (SEM) at different locations along the flame centerline. When the SiCl₄ concentration is 16 g/min, the particles first grow and then shrink with the flame temperature increasing. When the SiCl₄ concentration is 26 g/min, the flame temperature has little influence on the particle characteristics along the flame and many large spherical particles exist all the way.
