被撤回的出版物: Effect of ethylene glycol on hydrothermal formation of calcium sulfate hemihydrate whiskers with high aspect ratios(Retracted article. See vol. 6, pg. 99639, 2016)

The effect of ethylene glycol on hydrothermal formation of calcium sulfate hemihydrate (HH) with high aspect ratios was investigated in this work. HH whiskers with a preferential growth along the c axis and an average aspect ratio up to 400 were synthesized using oyster shells as raw materials in the presence of 3.76 x 10(-3) mol L-1 ethylene glycol. The preferential adsorption of ethylene glycol on the negative (200), (400), and (220) facets was confirmed by IR, XRD, XPS, and zeta potential measurements. The experimental results indicated that the adsorption of ethylene glycol promoted the 1-D growth of HH whiskers, leading to the formation of whiskers with high aspect ratios.
