Abstract

Basic copper carbonate [Cu2(OH)2CO3]with sphere-like morphology had been prepared via a direct precipitation route by controlled reaction conditions. Crude materials were cupric chloride solution and sodium carbonate solution. The factors like reaction temperature and reaction pH were studied. Scanning electron microscopy, powder X-ray diffraction, and Fourier transmission infrared spectrometry are used to characterize morphologies, crystal form and structure of the obtained malachite samples, respectively. The result shows: The obtained product is sphere-like malachite. These green basic copper carbonate crystal particles are formed with a diameter of 5.0~6.5 m, when the temperature keeps about 50 ºC , pH is about 7.0~7.5, and to react for 6h. And it promotes the crystallization of amorphous basic copper carbonate by adding malachite seeds. Cupric oxide can be obtained with the pyrolysis of as-prepared malachite microspheres, and the microspheres and surface microstructures of the malachite are preserved.
