| Abstract: Spindly calcium carbonate coated with AlOOH has been successfully prepared by bubbling carbonization method. SEM and XRD analysis results suggested an amorphous filiform the coating layer of AlOOH. Inverse gas chromatography (IGC) analysis indicated that γsD, the London component of surface energy of calcium carbonate increased after being coated with AlOOH, especially when with the coating weight quantity of 4%. And the reduction of the γsD value with the ascending column temperature became more obvious along with the increase of the coating weight quantity, which might be due to the desorption of water from the surface. In addition, the surface acid- alkali capacity of calcium carbonate also increased after coating. |
