Title
The Sintering Mechanism of Silver Spheres Line in Hydrogen
최성수 Sung Soo Choi
Abstract
A study on sintering between 730∼940℃ for 1∼250 hours in hydrogen was conducted by using spherical silver particles with an accuracy diameter 0.522㎜ and standard deviation 0.006㎜. In case published material data and sintering equations were used, it is shown that surface diffusion dominates the neck-growth stage of sintering for silver particles. The empirical suface diffusion sintering equation has been determined by measuring neck-growth rate, resulting in (x/a)^7 = [36 b_s γ_s ΩD_s/(kTa⁴)]t.
