IMPURITIES IN ZINC AND ZINC ALLOYS

Objective



The composition of zinc and its alloys is routinely determined by optical emission spectrometry. All types of emission spectrometer require series of calibrants covering a range of concentrations. The European zinc industry has used standards supplied by a French organisation for several decades. When these standards became exhausted, the BCR has accepted to produce and certify new series of reference materials for unalloyed zinc and for the zinc alloys ZnAl4 and ZnAl4 Cu1.

RESULTS

17 reference materials in the form of disks have been certified:

7 grades of unalloyed zinc(CRM 321 to 327; varying impurity levels)
5 grades of ZnAl4 (CRM 351 to 355; varying impurity levels)
6 grades of ZnAl4Cu1(CRM 356 to 361; varying impurity levels)
Certified elements: Al, Cd, Cu, Fe, In, Mg (alloys only), Ni (alloys only), Pb, Snand Tl.
Certification reports:EUR 12817 (1990) (unalloyed zinc) and EUR 12818 (1990) (zinc alloys)
