The solution pH shows strong effects on the size and morphology of the products. The products were characterized by X-ray power diffraction (XRD) and Scanning electron microscope (SEM). The infrared emissivity of Cu<sub>2</sub>O was tested by Far infrared emissivity measurer S302. The possible crystal growth processes have been proposed.展开更多
