| titleOfInvention | Vacuum thermal evaporation material mixing technique of superfine W-K metal powder |
| abstract | The invention belongs to the material mixing technology of powder material and especially relates to a vacuum thermal evaporation material mixing technique of superfine W-K metal powder. The technique comprises such steps as pretreating a quartz tube, encapsulating superfine W powder and K lumps in an ultralow oxygen glove box through the quartz tube, performing vacuum thermal evaporation treatment on the encapsulated sample, performing post treatment on the sample after the vacuum thermal evaporation treatment, and the like. The technique provided by the invention can uniformly mix the superfine W-K metal powder, and the mixed powder well keeps the initial granularity size; and the technique can realize the accurate control of millionth order of the ingredients of the K element. The invention provides an effective way of mixing the superfine metal powder, which is liable to oxidize, low in smelting point and is doped with trace elements, so that the technique has actual application value. |
