Abstract
Abstract Abstract Reactions of two nitrides, an oxide (α-SiaNi, A1N and α-AI2O3) and bath metals (platinum, iron and tin) in graphite capsules were investigated in vacuum fusion analysis by measuring gas extraction curves with a quadrupole mass spectrometer which can simultaneously measure nitrogen and carbon monoxide from the furnace. From the characteristic gas extraction patterns of each bath metals, gas release reaction mechanisms and their temperatures were studied. Key Words: Quadrupole mass spectrometerVacuum fusionGas extraction curvesSilicon nitrideAluminum nitrideAluminum oxide
