PROGRESS OF THE METHOD OF STANDARD CHEMICAL ANALYSIS OF ZIRCONIUM AND ZIRCONIUM ALLOY

The progress of the method of standard chemical analysis of zirconium and zirconium alloy in recent 20 years is reveiwed in this paper. The method sof analysis used in China,U. S. and Japan are to he compared, including (1) the amount of components of alloy and offoreign elements which are required to be analyzed and controlled and (2) the analytical methodused for various elements The following problems are discussed: (1) instrumental analysis beingthe chief symbol of modern analytical chomistryl (2) more attention being paid to the determi-nation of trace impurities (3) the allowable deviations of content of the clements in alloy (4)the practioality of the standard method of analysis (5) the neccssity of standard sample of zir-conium alloy (6) the necessity to establish the commercial standard of chemical analysis of zir-conium and zirconium alloy.
