An assessment of the difficulties in determining zirconium by various techniques indicates that X‐ray fluorescence analysis has several favourable characteristics, provided the technique can be calibrated reliably. After critical evaluation, a group of silicate reference materials was selected to calibrate energy dispersive X‐ray fluorescence instrumentation. The accuracy of the resultant calibration was verified by a standards addition procedure. New zirconium data were obtained on a wide range of reference samples and compared with values from recent compilations.
