Abstract
Determination of hydrogen, oxygen and nitrogen in metallic titanium were studied by the vacuum fusion method and the chlorine method. In the vacuum fusion method, hydrogen and oxygen were completely extracted and could be determined at 1850∼1900° by using iron bath, but nitrogen was not extracted. Then, in the chlorine method, oxygen could be determied by chlorination at 300° in a stream of mixed gases of chlorine at 5 mL/min and nitrogen at 20∼30 mL/min.
