Description
先ず、支持棒12を昇降装置15に取り付け、支持棒12の先端に取り付けられている出発ガラスロッド13を反応容器11内に納める。次に、昇降装置15によって出発ガラスロッド13を回転させながら、クラッド用バーナ18によってガラス微粒子を出発ガラスロッド13に堆積させる。出発ガラスロッド13上にガラス微粒子の堆積したガラス微粒子堆積体14は、昇降装置15によってガラス微粒子堆積体14の下端部の成長速度に合わせて、引き上げられる。
図2に示すように、クラッド用バーナ18で形成される、SiCl4等の原料ガスを含んだ火炎ガス流20は、ガラス微粒子堆積体14に当ってその方向が急激にガラス微粒子堆積体14の外側方向に曲がることになる。
(実施例)
実施例、比較例とも、下記のような材料を使用してガラス母材を製造する。なお、実施例1,2は、参考例1,2と読み替えるものとする。
・出発ガラスロッド;直径25mm、長さ1000mmの石英ガラス
・クラッド用バーナへの投入ガス;原料ガス…SiCl4(1〜7SLM)、火炎形成ガス…H2(100〜150SLM)、O2(150〜200SLM)、バーナシールガス…N2(20〜30SLM)
Claims (2)
