摘要：An induction plasma torch for making optical fibre preforms of pure or dopedsilica comprises a reaction tube (2) where the plasma (8) is formed, tube (2) beingencircled by an induction coil (7) and protected against thermal shocks by an inner lining(9) less than 2 mm thick and comprising mainly silica. The lining is formed by applying anaqueous solution, suspension or jelly to the tube wall to form a layer of solid particleswhich are then dried and fired, but below fusion temp.
