Vapor Pressure of Gallium, Stability of Gallium Suboxide Vapor, and Equilibria of Some Reactions Producing Gallium Suboxide Vapor

Vapor pressures of gallium in the literature are too high because formed in the reaction of gallium with the quartz effusion cells used for the measurements. Gallium was found to be less reactive with alumina than with quartz. Measurements in an alumina effusion cell gave vapor pressures for gallium that obey the expression
