This paper analyzes the common deoxidize methods of heating power, vacuum, adding medication in furnace and desorption, points out the advantages, shortcomings and usage range of every methods.
The thermal desorption spectra of propene and oxygen adsorbed on blue tungsten oxide WO_ (2.90) have been measured by means of flash heating the sample in ultra high vacuum.
The method comprises the following steps of: preparing and prefreezing materials, drying the materials by sublimation and desorption under vacuum, and hermetically conserving the materials.
