ABSTRACT:
The invention relates to a process for producing ultrapure doped vitreous silica for producing a preform for optical fibres. According to the invention, an ultrapure porous glass, glass obtained after its shaping, is used as the crude starting material in a deposition process of the plasma torch, grain by grain Verneuil type, for example, in order to complete a preform obtained by said process for the separation of phases and acid washing or etching of the glasses.
