A new high-pressure vessel (bomb) is described which uses nitrogen gas as the pressurizing medium and has the capability of measuring both the compensating pressure and the bomb temperature during heating. It is possible to dissolve quite large pieces (0.5 g) of unground (i.e., uncontaminated) single-crystal ..cap alpha..-alumina. The physical, electrical, and manufacturing properties of aluminas are all much affected by the levels of impurities present, and hence the determination of trace elements in these materials is of great practical importance.
