Preparation of superhydrophobic nanocalcite crystals using Box–Behnken design

Arabian Journal of Chemistry, 2019
AbstractSuperhydrophobic nanocalcite crystals were prepared via an adjusted aqueous reaction of CaO, CO2 gas and sodium oleate. Box–Behnken design was used to optimize the preparation parameters such as CaO concentration, CO2 gas flow rate and surfactant concentration. The results revealed that the produced CaCO3 is indexed to the calcite phase.
