SILVER PASTE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a silver paste composition which can be sintered at a low temperature and provides a silver sintered body having excellent bonding strength and heat conductivity after adhesion.SOLUTION: Provided is a silver paste composition comprising silver particles and a solvent, or silver particles, a solvent, and an additive, where at least one of the silver particles has a lattice strainη, determined by the formula (1) of a Williamson-Hall method, becomes 5.5×10or more:βcosθ=λ/D+2ηsinθ(1), where,βis the diffraction line width [rad];θis the diffraction angle [°];λis the wavelength of X ray (CuKαray)[1.54Å]; D is the crystallite diameter [Å]; andηis the lattice strain.
