【Abstract】 The study status on the preparation process of various methods to prepare silver-coated copper powder and the powder’s properties were overviewed. These methods include replacement,chemical reduction, replacement in combination with chemical deposition, melting atomization. The pretreatment method of copper powder was introduced.The technical indexes of seven kinds of flaked silver-coated copper powder with different silver content were listed, and all the powder was obtained by method of replacement in combination with chemical deposition. The applications and prospect of silver-coated copper powders were also proposed.更多还原
