Manufacturing method of powder for Ag / SnO2 electrical contact and manufacturing method of Ag / SnO2 electrical contact material

Japanese Patent JP6333098

B2

PROBLEM TO BE SOLVED: To manufacture an Ag/SnOelectric contact material having fine oxide particle, uniform distribution, environment friendly, relatively low in cost and good in conductivity and abrasion resistance.SOLUTION: There is provided a manufacturing method of an Ag/SnOelectric contact material including a process 1 for conducting high energy ball milling at a rolling speed of 800 to 1500 times/minute to a mixture powder by mixing tin oxide, lanthanum oxide and copper oxide with mass ratio of 1:0.08 to 0.5:0.05 to 0.7 to obtain a nanocomposite powder, a process 2 of conducting ball milling at the rolling speed of 100 to 300 times/minute to powder by blending 5 to 12 mass% of the nanocomposite powder obtained in the process 1 and 88 to 95 mass% of silver powder and mixing uniformly to put the silver powder in the nanocomposite powder, a process 3 of granulating the powder obtained in the process 3, a process 4 of conducting molding and sintering to the powder granulated in the process 3 and a process 5 of conducting annealing to the material obtained in the process 4.
