title: A high-temperature inert gas fusion apparatus.
abstract: A high-temperature inert gas fusion apparatus capable of operating at crucible temperatures as high as 3,100 degrees is described. While this apparatus has been used primarily for the determination of oxygen in pyrolytic carbon-coated uranium carbide particles, its usefulness is not limited to this type of material. It can be generally applied to the determination of oxygen and nitrogen in metals, alloys and other materials amenable to analysis by vacuum-fusion techniques. Analytical results obtained on steel and uranium carbide samples are presented. The apparatus, in its present form, has been in daily use for nearly 2 years. Down time during this period has been negligible. A total of 20 samples can be run in duplicate in an 8-hr shift.
