MINERALS OF BISMUTHINITE-STIBNITE SERIES WITH SPECIAL REFERENCE TO HOROBETSUITE FROM THE HOROBETSU MINE, HOKKAIDO, JAPAN
Horobetsuite occurs associated with free sulphur and iron sulphide minerals, in the sulphur deposit of Horobetsu Mine. The chemical formula of horobetsuite has been determined as (Bi, Sb)2S3. The molecular ratio of Bi2S3 to Sb2S3 varies between 9:11 and 13:7. The mineral is intermediate between bismuthinite and stibni…

Magnetic Fields in Small Ferrite Bodies with Applications to Microwave Cavities Containing Such Bodies
The microwave magnetic field in a small ferrite sphere and thin circular cylinder is found in first approximation. In a circularly polarized exciting field the internal field is again circularly polarized. The ratio of the internal field to the exciting field is 3(µ±α+2)-1 for the sphere and 2(µ±α+1)-1 for the cylinde…

Über die Beziehungen zwischen der Konstitution und den Eigenschaften von Alkylbenzolsulfonaten mit jeweils einer geraden oder verzweigten Alkylkette bis zu 18 Kohlenstoff‐Atomen I
Abstract Technisch wichtige Eigenschaften definierter, reiner Alkylsulfonate und einiger binärer Gemische wurden eingehend untersucht: Kritische Micellbildungskonzentration, Erniedrigung der Oberflächenspannung, Benetzungs‐, Schaum‐ und Waschvermögen. Die erhaltenen Ergebnisse werden ausführlich diskutiert.

The Anodic Treatment of Aluminum in Sulfuric Acid Solutions
High purity aluminum was anodized in sulfuric acid solutions at various concentrations (5– 50%), temperatures (10°– 50°C), time periods (2 – 60 min), and current densities (1.7 – 6.2 amp/dm 2 ). The coating weight, metal loss, coating ratio, sealing weight gain, dyed color, density, and coating chemical dissolution ra…
Thermoelectric Behavior of Nickel Oxide
Measurements have been made on the thermoelectric power of several nickel oxide samples containing foreign ions. Using an energy model recently proposed for nickel oxide, the effect of the nature and concentration of additions on the Fermi level, hole concentration, and mobility is derived and discussed. For most of t…
Magnetic Cooling
After a historical introduction the general principles of the magnetic cooling method are outlined. First, the case of the ideal paramagnetic salt is treated, and this is followed by a discussion of the electric and magnetic interaction effects which cause departures from ideal behaviour, and set a lower limit to the…
Ionic Equilibria between Clay and Dilute Salt Solutions
Abstract Theoretical considerations are presented for the evaluation of the free energy change that accompanies an exchange of cations between a clay and a solution. Also, a means is proposed for characterizing the effective concentration of the ionic atmosphere of a substance that exhibits cationic exchange. Results…
Factors Affecting the Formation of Anodic Oxide Coatings in Sulfuric Acid Electrolytes
The amount of sulfate found in anodic coatings formed on pure aluminum anodes in sulfuric acid electrolytes increased as the current density and concentration of acid increased, but decreased as the temperature was raised. Chemical analysis showed that the coatings consisted substantially of Al 2 O 3 and SO 3 with pra…

Effect of Porosity on Thermal Stress Fracture
Sintered alumina with from 4 to 50% porosity was prepared by incorporating crushed naphthalene in a casting slip. Thermal stress resistance was determined from the radial temperature difference required to fracture hollow cylinders under steady‐state conditions. Thermal stress resistance decreases with increasing poro…
The Crystallization of Anodic Tantalum Oxide Films in the Presence of a Strong Electric Field
Crystallization of amorphous anodic oxide films on tantalum may be accomplished by holding at temperatures in the neighborhood of room temperature provided a strong electric field is present in the film. This results in crystalline areas consisting of pie‐shaped polycrystalline segments surrounded by coiled‐up cylinde…
