About melting point of cuo
The melting point of cuo is 1326 degrees celsius. It is an inorganic solid with the formula: CuO (Cu2+), which is one of the stable oxides of copper. It is a black color, non-toxic and is soluble in water, alcohol, dilute acid, ammonium chloride, and potassium cyanide.
It has good chemical properties like corrosion resistance, oxidation resistance, low toxicity, and so on. It is also a good candidate for use in many applications such as gas sensors, catalysis, solar cells, emitters and electronic cathode materials.
Optical Properties of CuO Nanomaterials
It is an important topic for physicists and materials science engineers to study the optical properties of the nanomaterials as the nanocrystals of CuO show different absorption, luminescence, and band gap characteristics. The morphology of the nanocrystals plays a significant role in the optical behavior of CuO.
Photoluminescence and magnetic properties of CuO are hardly studied; however, the recent studies on the optical and magnetic properties of CuO single crystals have shown interesting and unique results. For example, CuO single crystals showed antiferromagnetic order at 213 K and ferromagnetic order at 230 K. Moreover, CuO shows a remarkable multiphonon band at wavenumber of 1130 cm-1 that was attributed to the inharmonic coupling between phonons.
Besides, it was found that the addition of CuO into the Al/MnO2 system would increase dramatically the gas content throughout the whole reaction process and improve the pressure and speed of flame injection so as to accelerate the overall combustion reaction. Then, CuO effect on the thermal behavior of the system was analyzed via theoretical calculations of Gibbs free energy and enthalpy changes. The resulting outputs indicated that raising the temperature difference between the system and the air would cause the melt front to advance faster and the stored energy levels would be higher.
