Synthesis and sintering properties of composite nano-Ag–Sn slurry

This topic prepared a composite nano-silver–tin slurry. According to the boiling point of dispersant, 300 °C is determined as sintering temperature. As amount tin added increases, shear strength Ag–Sn slurry gradually increases. When 1/20, reaches maximum 50 MPa. The increase in due strengthening second phase. exceeds drops sharply, mainly overgrowth Ag3Sn, product reaction silver and tin. porosity was measured accurately by Photoshop software. porosities pure silver, 5% tin, 10% samples are 21.8%, 16.8%, 12.5%, respectively. Brinell hardness with 20.60N/mm2 97.79N/mm2, After adding small nano-tin, its increased density, decreases, value Compared nano-silver slurry, performance improved. Therefore, it provides certain reference for preparation
