Preparation and characterization of CaO nanoparticles from Ca(OH)2 by direct thermal decomposition method

Synthesis of clamshell derived Ca(OH)2 nano-particles via simple surfactant-hydration treatment

“…Under this temperature, the particles with smaller size were formed as a result of high nucleation rate and low growth rate. It was observed that Ca(OH) 2 structure still remained intact after underwent subsequent thermal treatment, whereby the crystallinity of samples treated at 400°C increased with slight enlargement of crystallite size to 31 …”

“…Different studies were discussed on the preparation methods for Ca(OH) 2 nanoparticles including sonochemical technique [4,21], hydrogen plasma-metal reaction [5], sol-gel method [22][23][24], hydrothermal method [25], homogeneous and heterogeneous phase syntheses [26][27][28][29] and precipitation method [30,31]. However, these techniques come with its own limitations which are high cost of organic solvents and chemical reagents that required as CaO starting precursor.…”

Thermal and electrical characterization of composite metal oxides particles from periwinkle shell for dielectric application

“…Metal oxide micro-and nanoparticles are important materials due to their applications in several areas such as catalysis, sensors, optoelectronic materials and environmental remediation [1]. In a quest for polymeric insulation with improved dielectric and electrical properties, metal oxide particles in micro-and nano-sized were also found to have played a vital role.…”

“…CaO nanoparticles are often produced via thermal treatment of Ca(OH) 2 [11,14] or CaCO 3 [7,15] as precursors. They have also been prepared by calcination of Ca(OH) 2 which was synthesized by adding NaOH [1]. A report on the electrical properties of calcium oxide shows that the metal oxide has an electrical conductivity of 1 × 10 −6 S m −1 [16,17].…”

Synthesis of spherical copper-platinum nanoparticles by sonoelectrochemistry followed by conversion reaction

“…Nowadays a large range of nanoparticles production methods are available: chemical or physical vapor deposition (CVD [9] and PVD [10]), laser ablation [11], sol-gel and solvothermal synthesis [12], reduction in emulsion [13,14] and thermal decomposition [15]. Other simple ways of producing nanoparticles are classical electrochemistry -under pulsed current [16] or not [17] -and sonoelectrochemistry.…”
