| Zusammenfassung: | In a method of manufacturing optical fibre preforms by causing a chemical reaction to take place in a gaseous reaction mixture so as to form a coating on a glass substrate wherein the reaction is promoted by the production of a plasma, a non-volatile component of the reaction mixture is held within a dispenser tube (3) so that when it is evaporated by applying heat, it travels through perforations (11) in the dispenser tube (3) and reacts with the other components of the gaseous mixture. |
