Determination of the Diffusion Coefficient of Vapors by Means of a Microbalance

Thermal analysis

“…TG in self-generated atmospheres has been reviewed, several crucibles described for this mode of operation, and the technique applied to decomposition of PbO, PbCCb, and Mn-(0Hc)2-4H20 (836). The evaporation of oil-solvent mixtures (188), the determination of the diffusion coefficient of vapors in gases (79), and enthalpies of sublimation ( 8) have been determined. BaCh decomposition temperatures were determined by TG in pure O2 and in O2-N2 mixtures (886) and, from a plot of log p(02) vs. 1/T, enthalpies and entropies of reaction and the formation of BaCh were calculated.…”
