Abstract:
     This metal or non-metal micropowder with a dimeter of 0.1-44 micrometers is made up by making metal or non-metal block into coarse powder having a dimeter of 44 micrometers to 100 meshes by use of ball grinding, aerosolizing method, or chemical process, and other steps including screening, removing impurities, fine grinding, dewatering, drying, sorting and deoxidization. It features simple technology, increase of productivity by about 100 times, decreasing cost by about 50%, and high quality of product.
