| Abstract: | Several conventional and international methods for determinating oxygen contents in metal powders the values obtained by these methods and their effects on technology have been described. A detail comparison has bean made between the national standard GB 4164-84《Determination of Reducible Oxygen Contents by Hydrogen in Metal Powders and the current international and corresponding standards in various countries. GB4164-84 has the advantages of eliminating interference from carbon, wide range of applications, good efficiency of purification of hydrogen gas and rapid determination. |
