摘要:A key factor of preparing nano calcium sulfate is to employ a appropriate technology condition for forming reverse micelle microemulsion, which makes CaSO4 crystal grow with an ideal templating effect of reverse micelle. Homogeneous spherical nano CaSO4 with an average diameter of 70 nm were prepared by using reverse micelle microemulsion of AOT, OP-10 compound surfactants/cyclohexane/n-pentanol/water under mole ratio of water to surfactants 20, reactants concentration n([Ca2+])/n([SO42-])=0.125 mol/L and aging time 10 min. The influence factors such as the molar ratio of water to surfactants (ω), reactants concentration, n([Ca2+])/n([SO42-]) value, aging time t, etc. were also analyzed.
