Comparison of Thermal Behavior of Two Samples Basic Copper Carbonate


Thermal behavior of micro and nanoparticles of Basic Co […]

Thermal behavior of micro and nanoparticles of Basic Copper Carbonate (WSDTY) was studied under identical condition. The thermal properties of the samples. For microparticles of basic copper carbonate, DTA endothermic decomposition occurs at 291.5ºC, and the TG mass loss range is 230 - 330ºC. However, nano sample decomposed endothermically at 287.7ºC and its mass loss range is about 245 - 315ºC. Such behavior may indicate that the decomposition temperature range for nanoparticles is narrower than the microparticles. Also, the results showed that the decomposition temperature for the nano-sample is lower than the micro-sample.

We reported a novel method to obtain basic copper carbonate nanostructures by single-step oxidation of metallic copper on the anode, in the bicarbonate electrolyte, which is clean, mild and controllable. On the other hand, the conventional method is used for the production of copper carbonate micro-particles. The results of TG-DTA showed that the thermal decomposition of basic copper carbonate (micro and nano-particle) samples occur in the air in a single

step. However, copper carbonate nano-particles have a different decomposition temperature than the micro-particles, but both of them have a similar mass loss. Finally, from a viewpoint of practical application, this present study describes a process which can be easily scaled up for production of nano-sized basic copper carbonate powder.
