Abstract

L'invention concerne un procédé de fabrication d'une pièce semi-finie en SiO2, selon lequel, et conformément à la technique connue, des couches superposées de particules de SiO2 sont déposées, au moyen d'un brûleur à précipitation, sur la surface latérale d'un support entraîné en rotation autour de son axe longitudinal, de manière à former la pièce semi-finie, le support étant ensuite retiré. L'invention a pour but de faciliter l'enlèvement du support et de permettre ainsi la fabrication d'une pièce semi-finie en SiO2 (1) dont les parois intérieures soient pratiquement exemptes de défauts. En conséquence, l'invention est caractérisée en ce qu'on dépose une succession de couches dures (5) entourant la première couche, présentant une densité supérieure aux couches (6) suivantes appliquées sur ladite succession de couches dures (5). La pièce semi-finie poreuse en SiO2 selon l'invention est caractérisée en ce qu'elle comprend une région formant une âme (2) en verre de quartz poreux, formée d'une pluralité de couches successives, région qui est entourée coaxialement par au moins une région enveloppante (3) en verre de quartz poreux, en ce que la région en verre formant l'âme (2) présente une couche de verre intérieure (5) et une couche de verre extérieure (6) entourant la couche la plus intérieure, et en ce que la couche de verre intérieure (5) de l'âme présente une densité plus élevée par rapport à la couche de verre extérieure (6) de l'âme.
