This part of ISO 14720 defines a method for the determination of sulfur in powdered and granular non-oxidic ceramic raw materials and materials, which are completely oxidized at a higher temperature in an oxygen atmosphere, e.g. carbon and graphite materials.<\/p>\n
For materials which are not completely oxidizable under these conditions, it is possible to determine sulfur that can be released under these conditions, e.g. the adherent sulfur.<\/p>\n
This part of ISO 14720 is applicable for materials with mass fractions of sulfur \u2264 10 % and mass fractions of ash < 20 %, The defined method is limited for materials with mass fractions of barium < 10 mg\/kg, because the sulfur bonded in barium sulfate is not detectable with this method.<\/p>\n
For the lower detection limit of this method, a mass fraction of sulfur of 0,5 mg\/kg in the case of inductively coupled plasma optical emission spectrometry (ICP\/OES) and 5 mg\/kg in the case of ion chromatography (IC) has to be considered as a recommended value.<\/p>\n
