【Chinatungsten】tungsten copper electrolytic process


Processing
In the process of electrolyzation, use a certain proportion of NaCl, KCl, Na2WO4 and CuO4 mixed solution and graphite as electrode, the spacing electrode is 3cm, temperature controlled at 780 -800 . Under 0.5V-1.0V voltage reactants pre-electrolysis 1.5-2.0h voltage and adjusted to 2.5V-3.3V, continuous electrolysis 3h.

The electrolysis product was boiled with distilled out, after the addition of an appropriate amount of NaOH solution for soaking, filtering and drying to obtain final product. Finally, use X-ray diffraction analysis, scanning electron microscopy and energy dispersive spectroscopy to analyze the product phase, morphology and granularity.

Advantages

Copper particles are dispersed more evenly, no agglomeration occurs, smaller than the copper tungsten particles adhere to the larger particles of copper particles and is more tightly wrapped. The average copper tungsten powder particle sizes up to 0.9μm, sintering meets the industrial requirements totally.

【Chinatungsten】Cold Isostatic Pressing of Tungsten and Copper

Cold Isostatic Pressing, CIP, it refers to the isostatic pressing technique carried out at the room temperature. CIP usually uses rubber and plastics as mold wrapped materials, the liquid as the medium, the pressure is 100-630MPa, which mainly applied in powder molding. The purpose is to provide a sintered preform for the next process, such as forging or HIP process and so on. Compared with common molding process, tungsten copper CIP process has more uniform compacts and higher efficiency.
