Paints pigmented with zinc dust are no modern development—in fact, they have been known and used in the protection of iron and steelwork against corrosion for more than a century. During the last 15 years, however, this class of coating has assumed much greater industrial importance as research and development (much o…

The behavior of hafnium oxide was studied particularly in the temperature range 1500° to 18OO°C. Properties of HfO 2 at these temperatures and its reactions with ZrO 2 , SiO 2 , and CaO are given in terms of lattice and other physical measurements, many of which are new. Mono‐clinic hafnium oxide is stable to 1700°C.,…
A calculation is given of the indirect exchange ${\mathrm{I}}_{i}\ifmmode\cdot\else\textperiodcentered\fi{}{\mathrm{I}}_{j}$ type coupling of nuclear magnetic moments in a metal by means of the hyperfine interaction with the conduction electrons. The interaction appears to account qualitatively for the broad nuclear s…
Abstract The oxidation of iron, previously freed from oxide by hydrogen treatment, has been studied at 175 to 350° C; five methods (gravimetric, electrometric, film -transfer followed by chemical or microscopic examination, X -rays and electron diffraction) have been used to identify and estimate the different oxides.…
The unit cells of form C of long normal chain carboxylic acids with 12, 14, 18, 22 and 26 carbon atoms are determined, using powder methods. All dimensions in the monoclinic cell are found to be dependent of the number of carbon atoms in the chain. The a and b axes and the angle fl decrease asymptotically with increas…
