NOVELTY - A low-background conductive thermal embedding material comprises phenolic resin, conductive carbon medium and toughened carbon medium. USE - Low-background conductive thermal embedding material for scanning electron microscope used as surface analysis instrument for displaying internal structure of sample. ADVANTAGE - The embedding material has excellent electrical conductivity, suppressed serious charging effect and low element background, thus effectively improving the detection effect of samples, and is prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of embedding material, which involves providing mixed additive liquid, adding each component into the additive liquid, stirring and mixing until all components are mixed evenly, drying, and crushing into powder.
