摘要: A method and manufacturing apparatus for forming one or several material layers inside a basic tube, which basic tube is used in the manufacture of an optical fiber preform. The surface inside the basic tube is electrically charged by guiding a first electrically charged gas flow inside the basic tube, whereafter a second electrically charged gas flow is guided into the basic tube. The gas flow contains material particles and the sequentially alternating first gas flow and second gas flow have opposite charges.

摘要: A method for charging particles used for processing of a material. At least a gaseous reactant is supplied and oxidizing gas is supplied to the reactant. The oxidizing gas is charged electrically before it is supplied to the reactant. The reactant and the oxidizing gas form charged particles. The material to be processed is advantageously a multicomponent oxide construction, such as an optical fiber preform. The invention also related to a charging device implementing the method.
