Analysis of impurities in high-purity aluminum oxide by glow discharge mass spectrometry

A method has been developed for determining trace components in high-purity aluminum oxide powder for making sapphire single crystals. The analyses have been performed with VG9000 glow-discharge mass spectrometer which provided a sensitivity at the sub-ppm level. To analyze nonconducting specimens,...
