Resumen:
This document defines a method for the determination of sulfur in powdered and granular non-oxidic ceramic raw materials and materials, which are completely oxidised at higher temperature in an oxygen atmosphere, e. g. carbon and graphite materials. It is applicable to materials with mass fractions of sulphur less than or equal to 10 %, of ignition residue less than 20 % and of barium less than 10 mg/kg. Mass fractions of sulphur of 0,5 mg/kg when determined by ICP OES and of 5 mg/kg when determined by IC are guide values for the low application range of this method.
