“…The decomposition product of synthetic B-FeOOH (Akaganeite), particularly under vacuum or in an inert atmosphere, has recently been the subject of interest in different problems: first for a possibility of producing ferromagnetic acicular powder material suitable for magnetic tapes (1,2), and, second, for the investigation of pore formation by dehydration which is relevant to the adsorbability of gaseous molecules such as N2, CC]4 (3), H20 (4), and NO (5).…”

The synthetic β‐normalFeOOH (Akaganeite) was dehydrated at 300°–500°C for 1–20h under vacuum of 10−3 and 10−5 torr. The magnetic properties of the obtained dehydration products have been measured for saturation magnetization false(Mnormalsfalse) , residual magnetization false(Mnormalrfalse) , and coercive force false(Hnormalcfalse) . Mnormals and Mnormalr were proportional to the chemically analyzed Fe2+ content in the samples. With reference to the x‐ray diffraction results, it was found that the dehydrated products of β‐normalFeOOH in vacuo are the oxides in the Fe3O4 series containing different amounts of Fe2+ in the range 1–3 mmol g−1, and with a certain amount of α‐Fe2O3 . The oxidation of the dehydrated β‐normalFeOOH in air at 225°C for 20h gave oxides of the γ‐Fe2O3 series, which are entirely different in magnetic properties but almost similar in x‐ray reflections in comparison with those of the dehydrated β‐normalFeOOH . The variations of Hnormalc and the reduced remanence false(Mnormalr/Mnormalsfalse) with the Fe2+ content are also discussed.

“…Although costing studies have not been completed for liquids, it is expected that the junction forma- Much interest has been centered on the surface of compound semiconductors such as GaAs (1). Controlling the chemical, crystallographic, and electrical properties of the surface has become indispensable for realizing GaAs integrated circuits (2). One of the problems in GaAs IC fabrication, however, is to obtain uniformity of the electric properties for each device as well as a reproducibility from wafer to wafer.…”

Conventional gaseous BBr3 and CVD SiO2 are presently used in the Westinghouse baseline process for the production of high efficiency (13%–15%) dendritic web solar cells. The objective of this study was to replace the CVD SiO2 mask and the subsequent BBr3 diffusion step with a liquid SiO2/normalliquid boron dopant diffusion process. The number of process steps are reduced significantly with the use of the liquid process. Data on time‐temperature relationship on sheet resistance, junction depth, etc., were obtained and are presented. Various application techniques for the liquid process were investigated. As a first step, a manually applied sponge‐squeegee applicator was used, which was later replaced with a meniscus coating machine. This equipment permitted the application of uniform layers of liquid dopants of controlled thickness on the dendritic web. Various runs were made to make direct comparison of the liquid and baseline processes. The results of cell efficiencies achieved using the liquid process indicate that high efficiencies (13%–15%) can be achieved with this process. Results of VOC , ISC , fill factor, etc., are presented in detail and compared with the baseline process. Dark IV measurements made on liquid‐processed cells indicate excellent quality junctions and high lifetime values. The series and shunt resistance measurements on typical cells show no difference as compared with the baseline process. Junction profiles are presented for both a gaseous diffused cell and a liquid processed cell. The profiles show no dissimilarities.
