Abstract
Official abstract text for this publication.
The invention provides a production method for a glass particulate deposit M which includes a deposition step where a starting rod 111 and a burner 222 for production of glass particles 130 are installed in a reactor 102 , a glass source material is introduced into the burner 222 , the glass source material is subjected to flame thermal decomposition in the flame formed by the burner 222 to thereby form glass particles 130 , and the formed glass particles 130 are deposited on the starting rod 111 to produce a glass particulate deposit M. In the deposition step of the production method, at least two ejecting ports 231 are provided per one burner 222 for ejecting the glass source material from the burner 222 , and a flow rate of the glass source material jetting out through one glass source material ejecting port 231 is from 4 m/s to 60 m/s.
