| Abstract: | Using the wet ball mill process,the loose packed silver powder with low apparent density were prepared through adjusting the proportions of silver powders to the ball,the ball sizes and milling times.The flake silver powders prepared have low apparent density of less than 1.0 g/cm3,adjustable slice size and high specific surface.The flake silver powders have been applied successfully to prepare the silver paste,and pay important roles in reducing the silver content,improving paste viscosity and increasing the conductivity of the past. |
