CaO is an important material because of its application as catalyst and effective chemisorbents for toxic gases. In this research CaO nanoparticles were prepared via direct thermal decomposition method using Ca(OH)2 as a wet chemically synthesized precursor. Nanocrystalline particles of Ca(OH)2 have been obtained by adding 1 and 2 M NaOH aqueous solutions to 0.5 M CaCl2ㆍ2H2O aqueous solutions at 80 ℃. The precursor [Ca(OH)2] was calcined in N2 atmosphere at 650 ℃ for 1 h. Samples were characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), infrared spectrum (IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunaure.Emett.Teller (BET). SEM images showed that CaO nano-particles were nearly spherical in morphology. TEM images illustrated that produced CaO nano-particles had the mean particle size of 91 and 94 nm for 1 and 2 M NaOH concentration, respectively. As a result, this method could be used for production of CaO nano-particles on large-scale as a cheap and convenient way, without using any surfactant, organic medium or complicated equipment.
