Abstract:
The shacking time effect on the kaolinite material morphology, physical and grain size have been analyzed. The aim of this study was to synthesize kaolinite material from Indonesian kaolin to gain nanoscale particle reduction by shacking time and powder metallurgy cycle. Kaolinite particle powder was successfully synthesized from thick kaolin solution. The increase in the shacking time resulted in the homogenous dispersion of kaolinite particles, the reduction of grain size particle clustering, and the reduction of distances between its particles. The significant grain refining during shacking was revealed which showed reduction of particle size resulting from longer milling time. SEM analysis of the nanoparticle explained that designated ball shacking presents to the crystalline refining development. It can be discussed that these morphological and microstructural variations of Al2O3 2SiO4 2H2O particle powders developed by designated ball shacking time were found to present to an i
mprovement in the density, grain refinery, grain size of kaolinite material particle. The modification of particle grain size is possible into an initial nanoscale by employing shacking and milling powder metallurgy process. A significant reduction of grain size reduction was acquired in all cases.
