During the past few years there has been a rapid development in the chemical technology of epoxy resins. Currently, these resins are being widely manufactured and are available under a variety of trade names. Industrially the epoxy resins are important for use in corrosion-resistant surface coatings, molding compounds…
Abstract The rate of absorption of nitrogen peroxide into water at 25° and 40°C. has been found to be a linear function of the concentration of nitrogen tetroxide in the gas phase and directly proportional to the interfacial partial pressure of the same species. The rate of absorption is independent of gas velocity ov…

Abstract Various procedures were used for extraction of Al from Ohio soils representing a wide range in extractable Al. One normal NH 4 OAc at pH 4.8 was selected as an extracting solution because of its superiority over Ba(OAc) 2 and BaCl 2 . One normal NH 4 OAc plus 0.2 N BaCl 2 was no better than NH 4 OAc alone. At…
The solubility of Al(OH) 3 was measured in NaOH and HClO 4 solutions. Possible reactions of Al(OH) 3 in dilute NaOH and HCIO 4 solutions are indicated along with the calculated constants. The amphoteric hydroxide was found to be more acidic than basic. The isoelectric point of Al(OH) 3 was determined to be pH 7.7.

The oxidation of purified green silicon carbide in controlled atmospheres was studied by weight‐gain measurement and by observation of the surface reaction products, including optical measurement of the thickness of the oxide surface film. The rate of oxidation was much greater for silicon carbide in contact with flui…

Abstract A general method for describing the crystal orientation in a uniaxially oriented crystalline polymer is presented. It is shown that two orientation functions may be quantitatively evaluated from x‐ray diffraction data. The variation of these during mechanical and thermal treatment may be studied. These functi…

The refractive index of a sample of As2S3 was determined at three temperatures near 19°, 25°, and 31°C for selected wavelengths in the range 0.57 μ to 11.8 μ. A five term Sellmeier type dispersion equation was fitted to the averaged data reduced to 25°C; four of the constants were chosen to approximate an absorption c…

Measurements of the absorption spectrum of Si, made with high resolution, near the main absorption edge, at various temperatures between 4.2\ifmmode^\circ\else\textdegree\fi{}K and 415\ifmmode^\circ\else\textdegree\fi{}K, have revealed fine structure in the absorption on the long-wavelength side of this edge. This str…
Abstract From quantitative data reported by various investigators, it is concluded that the primary passive film on iron has the following properties: (1) 25–100 Å thick, (2) equivalent to 0.01 coulomb/cm 2 , (3) can oxidize CrO − 2 to CrO −− 4 , (4) follows the (Flade) potential relation —0.58 + .058 p H (volts).

The internal friction of BaTiO 3 ceramics has been studied under various conditions. It depends on temperature, biasing field and vibration amplitude, but is nearly independent of frequency and porosity. It is concluded that its main part is not caused by the ceramic and domain structures but is the property of the si…
