摘要： This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s). Results include constituents formed in the liquid including micron-sized particles and/or nanoparticles (e.g., metallic-based nanoparticles) of novel size, shape, composition and properties present in a liquid.

摘要： Provided is a dendritic silver-coated copper powder which is prevented from agglomeration, while ensuring excellent electrical conductivity by increasing contact points in cases where silver-coated dendritic copper powder particles are in contact with each other. This dendritic silver-coated copper powder is suitable for use in conductive pastes, electromagnetic shielding materials and the like. A dendritic silver-coated copper powder 1 according to the present invention has a dendritic form which comprises a linearly grown main trunk 2 and a plurality of branches 3 arising from the main trunk 2. The main trunk 2 and the branches 3 are configured of copper particles which have plate-like shapes having an average cross-sectional thickness of 0.2-1.0 μm, and the surfaces of which are coated with silver. This dendritic silver-coated copper powder 1 has an average particle diameter (D50) of 5.0-30 μm as determined by a laser diffraction/scattering particle size distribution measuring method.

摘要： To provide a copper powder exhibiting a high electric conductivity suitable for a metallic filler used in an electrically conductive paste, a resin for electromagnetic shielding, an antistatic coating, etc., and having excellent uniform dispersibility required for forming a paste so as to inhibit an increase in viscosity due to flocculation. This copper powder 1 forms a branch shape having a plurality of branches through the conglomeration of copper particles 2. The copper particles 2 have a spheroidal shape, with diameters ranging from 0.2 μm-0.5 μm, inclusive, and lengths ranging from 0.5 μm-2.0 μm, inclusive. The average particle diameter (D50) of the copper powder 1 in which the spheroidal copper particles 2 have conglomerated is 5.0 μm-20 μm. By mixing this tree-branch-shaped copper powder 1 into a resin, it is possible to produce an electrically conductive paste, etc., exhibiting excellent electric conductivity, for example.

摘要： A hydrometallurgical process is provided for the recovery of tellurium as elemental tellurium powder from copper refinery anode slime containing high amount of lead. The process involves the removal of copper and lead from anode slime followed by the recovery of tellurium as elemental powders. An economical and environment friendly process is provided for producing tellurium from a high lead bearing anode slime as it involves only hydrometallurgical techniques and thereby avoids emission of any polluting gases and has an efficiency of 85 to 90%. The developed process of recovering tellurium as elemental powders from copper refinery anode slime is beneficial in the production of pure tellurium instead of tellurium compounds. It helps raise the profit margin of a non-ferrous metal industry dealing with extraction of copper from ores and treatment of anode slime for the recovery of other metal values.
