A Method for Increasing Dissolution Rate of Tin Granule

摘要

insoluble anode electro-plated tin-plated in the plating process used to make up for the missing tin ions When dissolving metallic tin particles is reduced by introducing the second phase dissolves in the reaction system of the tin to a method for increasing the rate of dissolution of metallic tin particles. Palladium on titanium particles with a particle tin, platinum and at least one noble metal is coated with a noble metal-coated particles with particle diameter of 1~10 selected from the group consisting of the gold to the surface area ratio of the total surface area of the tin particles 10 to The dissolution rate of the particles is increased by the addition of tin to be 50%. ; Thus, it is possible to dissolve the tin using a small amount of oxygen as compared to the prior art, the amount of oxygen blown into the tin oxide is reduced sludge production is reduced to less than 1/3. Divalent tin by the oxygen blown into the tin 2 in the same amount of oxygen as the oxidation of the ions is reduced the amount of dissolved ions also increase.
