Tin–copper mixed metal oxide nanowires were successfully prepared by thermally oxidizing electrodeposited metallic nanowires (Sn–8 at.% Cu, Sn–43 at.% Cu and Sn–86 at.% Cu). The structure and composition of these nanowires before and after thermal oxidation were characterized by scanning ...
A mixed CuSn-10 powder is prepared from the prealloyed powder prepared from Cu powder and Sn powder by prealloying and the additive through proportional mixing. Its advantages are high uniformity, low segregation rate and content of oxygen, and low cost.江建平...
