| Description | The effects of ultrasonic milling, dry and wet ball milling, and vibro-milling on the particulate properties, crystalline characteristics, morphology, and surface area of clinoptilolite (Cpt) have been investigated. Laser beam scattering technique, X-ray diffraction (XRD), scanning electron microscopy (SEM), and nitrogen adsorption/desorption at 77 K are used to characterize the initial and ground Cpt powders. Results show that Cpt particle size is significantly reduced by all carried out milling methods in which vibro-milling could produce particles with diameter less than 100 nm. The size distribution of Cpt is remarkably narrowed by using vibro- and wet ball milling. The crystallinity of Cpt noticeably decreases for the samples obtained by ball milling while vibro- and ultrasonic millings show a negligible effect on crystallinity. The specific surface area of Cpt is enhanced by all four milling methods. |
