Abstract ENGELHARD ALLOY 15065, also known as Silver Mag Nickel and Spring Silver, is a vacuum-melted alloy of silver, magnesium and nickel which may be oxidation hardened to produce good spring and electrical conductance properties. It is recommended for high-electrical-conductivity, corrosion-resistant springs and switches. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: Ag-5. Producer or source: H.A. Wilson Division Engelhard Industries.

Some physical properties of ferric chloride-dimethyl sulfone (FeCl3-DMSO2) melts were investigated. The phase diagram was determined by differential scanning calorimeter and thermogravimetric analyzer. The electric conductivity, measured with computerized direct-current method, increased with increasing temperature and DMSO2 content. The conductivity was maximal (0.02149 S/cm) at 115 °C for 30 mol% FeCl3. The densities of all melts decreased with increasing temperature and DMSO2 content. The equivalent conductivities were given by Λ = κMmix/ρ, where Mmix is the mean equivalent weight of the binary melts. These equivalent conductivities were fitted by the equationΛ =Λoexp(−EΛ /RT), where the activation energies EΛ were 8.63, 22.94, 25.92 kJ/mol for 30, 40, 50 mol% FeCl3, respectively.

ABSTRACTNew naphthalene-sulfur compounds, oligomers of poly (l,4-naphthylene sulfide), have been synthesized and studied by electronic and vibrational spectroscopy in both pristine and oxidized forms. It has been found that the charged defects induced on these molecules are Much More stable than in the corresponding 1,4-phenylene derivatives. Nevertheless their physical properties are strongly affected by steric effects which hinder a regular arrangement of the repeating units.

In the present work some physical properties of binary zinc chloride-dimethylsulfone (ZnCl2- DMSO2) melts were investigated; the phase diagram was determined by Differential Scanning Calorimeter (DSC) and Thermogravimetric Analyzer (TGA) analyses; the electric conductivity was measured using a direct-current computerized method. The conductivities of the melts increased with increasing temperature and DMSO2 content. There was a maximum of the conductivity at 40 mol% ZnCl2; the conductivity was 0.00423 S/cm at 110 ◦C. The density of all the melts decreased with increasing temperature and DMSO2 contents. The equivalent conductivities were given by Λ =κMmix/ρ, where Mmix is the mean equivalent weight. These equivalent conductivities were fitted by the Arrhenius equation, where the activation energies were 25.2, 34.6, 44.5, 53.7 kJ/mol for 40, 50, 60, 70 mol% ZnCl2, respectively.
