Abstract
CaO is an important inorganic material, which can be applied into many aspects, such as catalysis, toxic-waste remediation, adsorbents etc. In order to make use of CaO, nano-CaO was prepared by sonication method using Ca(CH3COO)2.2H2Oas precursor, NaOH aqueous solution as precipitant in this paper. Characteristics of samples were measured by TGA, XRD, TEM etc. techniques. The results showed that the size of nano-CaO 140 nm could be obtained under the conditions (calcination temperature 530 °C., calcination time 15 h, heating rate of calcination 3 °C. /min). It is a very simple and effective method to prepare nano-CaO.
