【発明の名称】低い酸素分圧を有する制御された雰囲気を作成する方法及び装置
Document Type and Number:
Japanese Patent JP2002510355
Kind Code:
A
Abstract:
The present invention concerns a method for producing a controlled atmosphere having an oxygen partial pressure of below 10<-13> Pa and an operating temperature above 1000 DEG C. According to the invention a furnace is vented by a gas mixture having an oxygen partial pressure lower than 10<-8> Pa but higher than that of said controlled atmosphere, and that a partial volume of said furnace is submitted to a static electric field having a strength of at least 6 V/cm and reducing the oxygen partial pressure in this partial volume by orders of magnitude. The invention also relates to a device for implementing this method.
