§ 14. The Chemical Properties of Platinum
A. Jaquerod and F. L». Perrot, 1 F. Soddy, H. Damianovich, and H. Damianovich
and J. J. Trillat, observed that platinum absorbs a small proportion of helium.
W. Ramsay, and M. W. Travers observed that helium does not diffuse through
heated platinum. H. Damianovich and co-workers, and J. Piazza studied the
action of helium. A. Fery observed the effect of helium adsorption on the resistance
of the metal. According to R. Salvia, cathodic spluttered platinum deposited in
the presence of helium has a face-centred cubic lattice, and there is not space in
the lattice for the entry of helium atoms. H. Damianovich noted the change in
the microstructure of platinum in an electric discharge in helium. R. W. Lawson
showed that platinum electrodes in helium absorb a little gas, and similar results
were obtained with neon. W. Ramsay, and M. W. Travers found that argon does
not diffuse through heated platinum. J. C. Stimson, and G. I. Finch and
J. C. Stimson studied the subject. The adsorption of argon by platinum was
observed by M. W. Travers to be very small. The absorption of argon by the
electrodes in discharge tubes was discussed by L. Troost and L. Ouvrard, B. Brauner,
S. Friedlander, J. M. Eder and E. Valenta, and H. Kayser ; and of krypton, by
J. N. Collie, E. C. C. BaIy, and S. Valentiner and R. Schmidt, and likewise also
with xenon. W. Ramsay and co-workers, and V. Kohlschtitter and co-workers,
observed no combination with helium, neon, argon, krypton, and xenon.
J. N. Collie suggested the possibility of a combination with xenon. F. Fischer
and co-workers observed no sign of a combination with argon when platinum
is spluttered in liquid argon. W. T. Cooke, and W. Frankenburger and co-workers
studied the subject. H. Damianovich and co-workers compared the action of
helium on platinum in an electric discharge with the product in oxygen, nitrogen,
