| Abstract: | The alloy test specimen is dissolved by the Hydrochloric Acid, and adjusts the pH value with the Ammonia water and the Hydrochloric Acid to 2.5, reduces Iron with Antiscorbutic Acid. It takes the Xylenol Orange as the indicator to titrate Scandium with EDTA. This method is suitable for As - Sc alloy containing 1% - 20%Sc, and it is also simple,fastand accurate. |
