A Critical Study of the Soot Deposition Rate in ACVD Process

Atmospheric Chemical Vapor Deposition (ACVD) process is widely used for silica soot deposition in the manufacture of optical fiber. In the present work a series of experiments were done on the ACVD lathe to study the deposition rate. Target core rod diameter, number of burners, distance between the burners and the distance between the target core rod and the burners were found the key parameters affecting the deposition rate. Average deposition rate of 30.2 gm/min with a material efficiency of 34% were achieved in three-burner experiment.
