Abstract
The invention discloses a method for producing nano-copper oxide powder. The method comprises the procedures of (1) the preparation of a liquor: copper sulfate and ammonium bicarbonate are respectively prepared into the liquor with certain concentration according to required amount and the two liquor are respectively placed into a reactor and a container after being filtered; (2) reaction: while the liquor is stirred, an ammonia bicarbonate liquor is dropped into the reactor until the reaction is finished so as to obtain basic cupric carbonate sediment; (3) filtration: the obtained basic cupric carbonate sediment is washed and then detected to the extent that no sulphate ions exist in filtered fluid; (4) high-temperature roasting: the basic cupric carbonate sediment after being washed is dried and roasted at high temperature and the basic carbonate copper is converted into the nano-copper oxide powder. The method of the invention has simple production technology and low production cost, and the produced nano-copper oxide powder has good quality.
