摘要
Abstract
The flake silver powders were grinded by stirring ball milling with different milling aids at different milling times, using the precursors in different specific surface areas. The physical properties and electrical conductivity of flake silver powders were investigated by laser particle size distribution (PSD) instrument, scanning electron microscope (SEM), specific surface area (SSA) tester, and the test devices for apparent density and tap density. In the results, when the ball mill medium and the ball-to-powder weight ratio are determined, the flake silver powders with the sheet resistance no more than 15 ?/□ can be prepared by using spherical silver powders as the precursor with the excellent dispersibility at the specific surface area of ～0.50 m2/g, the stearic acid is chosen as the milling aids, and the milling time is controlled as 12 h. The prepared flake silver powders are suitable for the conductive silver paste production.关键词
