ABSTRACT

Nano-crystalline slaked lime was synthesized using design of experiment. In order to synthesize slaked lime, calcium chloride (CaCl₂) and urea were used as starting materials. Calcium chloride solution and urea solution were mixed and heated in vessel that calcium carbonate was precipitated during heating. Precipitates were filtered, washed several times using D.I.water and ethanol and finally dried in oven. Slaked lime (Ca(OH)₂) has been fabricated by the hydration of calcined CaCO₃. Design of experiment (Taguchi method) was used to optimize parameter, to minimize noise factors of experiment and to statistically analyze the results. Slaked lime having about 50 nm in ptimized crystallite size could be obtained by calcination of CaCO₃at 1000oC for 0.5 h and hydration with D.I water containing ethanol and oxalic acid.
