Preparation of nano-basic cooper carbonate with different size

Using copper sulfate pentahydrate and sodium carbonate as raw materials,nano-Cu2(OH)2CO3 with different sizes was prepared by direct precipitation method and the effect of the temperature of reaction and reactant concentration on the partice size was researched.The results showed that when the reaction temperature was in the range of 45~75 ℃ and reactant concentration was in the range of 1~2.5 mol/L,nano-Cu2(OH)2CO3 with different sizes can be prepared and the range of average particle size was 16 ~ 54 nm.In the process of the reaction,the reaction temperature and reactant concentration have a significant effect on the partice size.With the increase of reaction temperature,particle size decreases and with the increase of reactant concentration,particle size increases.
