Abstract: The optical fiber glass preform is prepd. by heat treatment in fluorine-contg. atmos. of shoot preform. Fine glass particles deposit is impregnated with fluorine at such a temp. that it is kept in porous state, is then vitrified under a F compound-contg. atmos. in a furnace at 1100-1400 C. The glass particles deposits are uniformly doped wiht F, and impurity content of the preform is lowered in a large extent.
Abstract translation: 制备光纤玻璃预制棒。 通过氟处理。 ATMOS。 的预制棒。 在这样的温度下，精细玻璃颗粒沉积物被氟浸渍。 保持多孔状态，然后在F化合物下玻璃化。 ATMOS。 在1100-1400℃的炉中。玻璃颗粒沉积物与F均匀掺杂，并且预成型体的杂质含量在很大程度上降低。
