Fusing of silver (Ag) nanoparticles synthesized in an aqueous system was observed at room temperature using halide solutions. The as-synthesized Ag nanoparticles have an average diameter of about 24 nm. After dispersing the Ag nanoparticles in a halide solution, a significant increase in particle size to about 188-197 nm was observed. The enlargement of particle size was accompanied by the increase in conductivity of the Ag nanoparticle ink. The resistance was reduced from 110 kiloohms to 35 and 9.3 ohms for the as-prepared and sintered Ag nanoparticles using NaBr and NaCl solution, respectively.

Low Temperature Process

An electrolytic sulfurization at room temperature has been introduced in the present work, which process parameters are optimized to the quenched Cr12 substrate. Morphology and microstructure of the sulfide layers are investigated deeply, and their formation mechanism is discussed in detailed. According to optimum parameter of sulfurizing process ( assistant current density of 1.8A/dm2, the saturated rare-earth-halide solution containing 300g Na2S2O3, 60g KHSO3 and 1000ml H2O, 298K/20~40min), the ferrous sulfide coating was easily obtained on the quenched Cr12 substrate with a uniform thickness of above 10μm, no matter about the treated parts with the complex geometrical shapes. The tribological experiment results of a block-on-ring tribometer indicate that the sulfide coatings on hard substrate have a very low friction coefficient and could obviously reduce the wear extent of its counterpart. Compared with the traditional low-temperature process, this sulfurizing technology has such virtues as simple process, heatless, low cost, little deformation, without pollution question, etc., which could be employed for industrial solid lubricant due to the good friction-reducing characteristic of lamellar-structure FeS phase.

A new method is proposed for the determination of milligram amounts of each halide present in a mixture of alkali-metal halides. In some mixtures, thiocyanate also may be determined. A methanol solution of the sample is titrated in a closed-type cell, with a standard solution of silver nitrate in methanol. By using high-frequency titrimetry, and an appropriate concentration of the halide solution, sharp end points were obtained for each halide. Because of solid solutions, the accuracy of the determination of individual halides in mixtures depended on the mole ratios of the halides; the errors found in the titration of various binary, ternary, and quaternary mixtures are reported. For some binary mixtures, the total amount of halide titrated in 120 ml of methanol was varied from 0.5 to 500 micromoles. At the lower concentrations, addition of a small amount of sodium nitrate sharpened the end point. At all concentrations of halide, an excessive amount of indifferent electrolyte essentially eliminated the end points. The alkali-metal halides gave more satisfactory titration graphs than did some other metal halides. The effects of variation in temperature, and of solvent evaporation were noted.
