The sonicated talc exhibited severe delamination and reduction of the plate diameter in the lateral dimension. The density of sonicated particles was reduced to 1.64g/cm3 when sonicated in acid for 40h. Particles sonicated in the watermedium also exhibited higher aspect ratios compared to those sonicated in the acid medium. The sonicated particles exhibited structural changes where the degree of crystallinity especially in (00l) planes were reduced; there were also decreases in crystallite size and increases in lattice strain for both media. Acid media sonication led to a lower degree of crystallinity compared to that in the water medium. The sonicated particles likewise exhibited shrinkage in lattice parameters for both media. Sonicated talc particles exhibited reduction of intensity for Mg-OH and OH stretching bands, but Si-O remained almost unaffected after 40h. Besides that, talc sonicated in both medium exhibited reduction in density and acid based sonicated talc shows the lower density of about 1.64g/cm3 due to leaching of magnesium. 2014-06-06T03:43:19Z 2014-06-06T03:43:19Z 2011 Article Applied Clay Science, vol.51(4), 2011, pages 399-406 01691317 http://www.sciencedirect.com/science/article/pii/S0169131710004229 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35133 10.1016/j.clay.2010.12.006 en Elsevier BV
